A huge factor for the longevity of this Million mile engine is the operating regime. 10k in a week means very few cold starts. In the old days, Mercedes handed out badges for every 250k and most taxis with the famous 4 and 5 cyinder pre-chamber diesels had several of them stuck on the radiator grille. Those engines were not shut off for several days as several drivers would operate the same taxi owned by the dispatcher. The current Mercedes-Benz High Mileage champ is Gregorios Sachinidis, a Greek taxi driver who holds the known record of more than 2.8 million miles in his 1976 Mercedes-Benz 240D. I can guarantee that he did not use the current Lucas additive.
Rotella is premium stuff - no argument there. We need a comparison between two identical trucks, driven in a very similar way, one with Lucas the other one without to see what difference the additive makes.
Great channel, I watch your videos often. I use Opti-Lube XPD with Valvoline Cummins Premium Blue Diesel Engine Oil. I’m going to send a used sample to BlackStone soon for analysis. We’ll see what results I get.
Hey Rich, the newer rotella formula no longer has the api rating for gas engines. Would you still recommend running rotella in a old school gas engine even though it is specifically catered to diesel engines?
97 4.6l ford gasser. 480,000 miles currently sittin with a bad clutch slave. All original engine miles, no smoke, still gets good mileage, its been overheated by me 2x in last four years to the point itnwas pinging and stalled. No oil leaks, i use cheapest oil oreillys has when im doing an annual change. Truck gets 35k a year on the log book pulling trailers last 4 years ive owned it. I use the truck to pull single axle lawn service trailer usually loaded around 3.5k. City and highway miles. Did the 5 speed manual at home when i bought the truck 280,000 miles ago. True story.
Most people don’t need a diesel truck, not even a 3/4 ton. What they don’t realize is the same reason grandpa drove an overloaded 1/2 ton pickup on the farm. Everything on the 3/4 and 1 trucks are expensive as hell, and if you don’t make money with your truck, I mean serious cash, it’s a big waste of money owning one. As reliable as they are, try a $425 brake line or go the shitty Dorman route and new calipers with brackets, you still got $850 for parts in just the rear brake job. That’s not counting if anything goes wrong with the diesel, say you get some contaminated fuel, you better have a big credit card if you break down. The overhead on these trucks is why you may not want to use it as your daily driver. Reliable Yeap, and expensive! Let the man with the big hairy balls (aka boss man) ride around town in that big truck, he can afford it. For what it is the half ton pickup does a hell of a lot and it can be your daily driver. I’ve even seen an old Toyota loaded down with cross ties and a Nissan pulling a 10,000 lb trailer with a tractor on the back. Not saying you should do that, but these are more of an everyday truck.
You could buy the biggest baddest truck on the lot, but if you have no money left over to buy food and live, what good is it. A mobile mechanic driving a 4x4 diesel truck has to charge you 4 times as much as a mechanic who drives an old Dakota. Regulations caught up with hotshot trucking decades ago, it cost a fortune and the loads don’t pay that much. In fact it cost as much as a Freightliner but hauls a fraction of the weight. The house trailer hauler truck might have a million miles, but most sit all week in the yard waiting on a sucker to get financing on a mobile home. The rest of the time he’s either cleaning up or sitting at home not getting paid. The only one making money is the finance manger! Like a used car lot, it’s easy to sell a car or truck, but try selling an $8000 truck for $14,995 plus tax tag and title.
Rotella 15w40,one of the best oils on the market for heavy duty diesel engine applications.BUT,i believe regular oil changes are key to longevity.ALSO,oil filters are not created equally.FLEETGUARD makes some of the best commercial,industrial filters out there.The difference comes with length of pleating in the filter,and the anti drain construction on the filter for cold engine starts.Have you ever bought an oil filter and noticed its shorter than the OEM filter?Run em' hot,and regular changes,thats the key.
I run a small pipeline outfit. We run nothing but rotello 15-40. I’ve got a 1992 Cat el300 excavator with around 18k hours on it. The motors never been touched. No turbo, no injections, only smokes for 15 sec on a cold start. Oil changes every 250hrs. Cat filters only.
Not sure how get In touch via email. Would like to pick your brain on a 2015 ram 2500 5.7 hemi... is like to swap it to the 5.9 Cummins. Only problem I’m worried is about getting the body control module to function correctly. I’d like to keep the gauges, touch screen radio and all the other features it has. Any info you have would be sweet
After watching that oil additive video I would like to say I bought 94 Dodge 2500 with a Cummins in 95 it had 22000 miles on it I ran shell for the first probably about a hundred and ten thousand miles ended up getting a knock kind of a bad tick in the engine really I switch to that Valvoline blue The tick in the engine disappeared never came back needless to say I'm done with shell
I absolutely love the channel, you’re a fellow SWO neighbor and a lover of mechanical diesels, so naturally I love the channel!!!
Have you ever worked on any of the old CDM spec Toyota Land Cruisers, they are 3rd works reliable have been imported by the boat load in several models for mining and were sold in Canada until 86 and that model still to this day are made , every body panel and most interior bits even fit until a couple year ago.
I spent a couple years over seas and cruisers are the rest of the worlds work horses. They are Cummins reliable! Especially the hino motors all built on a one ton truck chassis and power train. They are the truck that guys like you and I have wanted to buy and think no one has ever built them. Truth is they have sold them in massive numbers and they are the longest running model in history.
Would make an amazing channel project, You can buy mine trucks cheap but they are usually pretty trashed when the mines are done with them. Basically you can get pickups, short wheel base, medium and troopy as well as other variants.
Anyway here we go!
I have had two w124 mercs with 3 litre diesels (om603). Both of them had over 700 000km in the clock when i sold them. I've seen those engines go over million miles. Nowdays i'm rocking in vw golf 1.9 TDI, it has only 500k on the clock, but it engreases 80k per year.
In my old Peugeot diesel I just bought what ever good quality synthetic was on offer in either a 10w40 or 5w40 and used that,
My personal opinion is that you cant go wrong with any of the well established synthetic oils,
I'd say just warm up your engine properly and change your oil often, and you'll have many many miles out of it
Before anyone spends their money on Lucas Oil Stabilizer they should look at an oil analysis of the product. There's nothing in the bottle except un-additized bright stock. All that Lucas Oil Stabilizer does is dilute the additive package and increase the viscosity. Most engines don't need an SAE40 oil so a viscosity increase is not needed or wanted. Plenty of HD diesel engines are now specifying 10W-30 and oil analysis shows that it works.
Optilube XL is the fuel additive I use. It increases lubricity the most of any additive. That and Archoil 9100 in the oil (Delo Full synthetic), and I get 24 mpg out of my 7.3 IDI 1990 F250 XLT Lariat 4x4
Shell Rotella and a bottle of Lucas engine break-in juice every oil change and my 5.3 Tahoe is rolling onto 500,000kms in Alberta. And she works let me tell Ya she works. Lol never even considered anything but for my mills
6.0 or a 6.4 with a million miles? Not likely. I do know the IH versions of those motors in School Buses have done a million miles, but those are detuned versions of the engines Ford used. School buses with IH motors are running in Mexico and they run the hell out of them. But a Ford tuned IH that is not a 7.3, could have a million miles on the frame, but I am 100% sure the blocks never made it that long.
Have 631,000 miles on my isx15 and it always gets rotella t4 15w-40 and Lucas srabilizer every 30,000 miles which happens every 5 weeks. Been good to me so far. Also run rotella and Lucas in my 08 ram 6.7 Cummins but it's only got 70,000 on it.
I've got a 95 Nissan pickup with the VG30E. I don't know what the previous owners ran in it for oil, but I use Castrol GTX. Discovered that my year old Castrol went from 4.7Q to less than one quart by the time I changed it. Driven daily at an average of about 10 miles a day, usually 5 miles, but sometimes 80. Guam is a small island, but it's always more than enough to warm the engine up before I'm even a quarter of the way done with my commute. I'm not easy on the throttle either, I regularly get the truck into 5K passing other drivers. Even with that little of oil in the engine, it made no unusual noise and had no unusual wear when I was pulling the engine apart for unrelated work.
I'm not sure if that's a testament to the oil, or the engine design, but it's defiantly something. No additives besides random fuel cleaners, be it Lucas, Berryman's, whatever is available, every month to two months since I've owed the truck as of two years ago.
In Australia the Ford 4.0L inline six (known in its later forms as a Barra) was used in countless taxis, set up to run on LPG/Propane. Many of these cabs would hit the 1M kilometre mark, and theres plenty of rumors that at least one or two in Melbourne made it to the 1.6m km (near as well be 1M Mile).
Been running rotella for over 200,000 miles and Lucas additive for 40,000 miles, oil sample says it’s still a very health 24v with 240,000 miles on it, I even run rotella in my gassers because they’re older
I put three quarters of a million miles on a Dodge 318 using Lucas additive I know it's a gas motor but just the fact that I use Lucas I think help that motor out also idling that motor while I would sleep at night doing hot shot service..
Motul 8100 x-cess 5w-40 in my Audi 2.7T. Many of us Audi guys run Rotella T6 with great success! As far as additives, I use and recommend to my customers BG products such as EPR, MOA, 44K. I have a sales rep who comes to me, Napa sells some of them as well. I also use lubeguard in almost every transmission service for myself or customers.
I have used lucas for almost 20 years. It started out in a budget build 4cyl modified using a 2.3 ford motor and trans, I couldn't(money went into the motor) afford an aftermarket trans so I used a junkyard special and used lucas in it, and it outlasted any of the competitors transmissions (both stock and aftermarket) running comparable horsepower motors. I have used it every daily driver ever since. I also use the combination of Rotella T and lucas in my 5.7 K1500 and its up to 240k miles with no sign of slowing down.
Totally agree, and i could tell the difference when my Nighthawk 750 had lucas in the fuel that bike had over 80k on it and still ran super strong when the drive chain cracked the case. Oh btw i beat the shit outta that bike every day, it lived up near redline. All the rest of my bikes and cars have used full synthetic shell rotella, i won't run anything else, and it always performed flawlessly.
I have a regular customer that brings me work on a regular basis with his 05 6.0 psd excursion. When I painted the excursion last year it had 542,000 miles on it. Origional head gaskets and transmission. Seen bills from all over the country for oil changes so it's hard to say what all has been thru the engine. But I know for sure it gets motorcraft atf with Lucas additive every 50,000m. Local shop does maintenance on it when he's in town. It's not worked very hard but it does pull car trailers, boats, and campers on occasion.
There is a video out there showing a Jeep Cherokee with the 4.0 engine at 600,000 miles. If any gas engine could reach 1 million it would be a 4.0L. A guy i used to work his father had a old 70s deuce and a half with like 700,000 miles. Unsure if it was gas or diesel.
I had a 94 f250 that hit 750000km, still ran but used almost as much oil as fuel lol Iv always used Lucas in everything, I drive old worn out crap and it keeps them going for much longer than they should
Same here rotella and Lucas are the best have over half million miles on my Cummins with it and my dad's semi has 1.2 million miles on it with rotella and Lucas since new and the motor has never been cracked open. That's pulling lowboy all it's life with oversized loads grossing 100-150k combined weight still runs like new. Thanks for the great content.
2003 ram 2500 CUMMINS 427,500. Amsoil & good 45 Ce fuel also been tuned for 100,000 fass150gph fuel system for the last 17,500 miles truck runs great & pulls harder ever time I put my foot down .."all the time " only 1 trans at 379,000 ... yeahhhhhhh ONLY 1 TRANSMISSION
You would think Lucas would throw the chemistry of the oil off. Are the oil companys full of shit when they say not to use oil additives? What would be the benefit of Lucas in this Cummins. What did the additive do? Besides bring it to over a Million miles. LOL. Really though what does it do.
i have a little over 400k on a 1/2 tonne ram with a built up hemi. pennzoil in the engine and diffs, any atf4 in pws or t case, shell 89 in the tank, redline c plus in the moderately built tranny. any nigl2 molly lube in the ball joints and what not. napa gold/wix fluid filter. i find those are as good as youll ever get. lucas oil is crap. if it really was magic the other companies would analyse it and add a similar thing to their oil. look at heavy industry or mining, no lucas oil garbage. just use good oil and give it a little shake before pouring, couldn't pay me to put that crap in anything. just snake oil; if your using good lube and put that garbage in your doing more harm than anything.
Anthony Youngblood in grain valley Missouri. He owns super duty service. His personal truck has a 6.0 with 800,000 plus miles on it. He used to deliver campers before he got into the shop. Has had a set of head gaskets and studs done but I believe that’s it. He has videos on YouTube several of his own truck. Not a million miles but damn close
I'm running a 1998.5 dodge with a 5.9 24 valve cummins and It has been on the rotella diet for a very long time. It has just under 300,000 miles on it and I had to pull the oil pan to change the oil pan gasket and it looked amazing in the engine. There was great cross hatching in the cylinders and everything else looked great. I was going to change to a full synthetic oil later on but as you said the proof is in the pudding that oil just straight up works and works great.
Ive been using Lucas for years on bolth my 01 3500s. My 4wd has 300k miles and blowby and poors oil,(needs Tappet Cover )but shes still pulling like a train with those 4.10s and tuner.(parked now) My 2wd is bone stock,nvr had a tuner on it and is at 189k miles doesnt leak a drop of oil. Keep hoping you will do a Tappet Cover one of these day. Love yr videos nice and straight to the point for us working folk.
I run only Rotella 15-40 in my 5.9 Cummins CR. Haven't tried any Lucas yet. Do you just use a gallon of Lucas in place of a gal of Rotella? I always run Stanadyne fuel additive. Is the Lucas fuel additive the same as the gas additive or do they make one specifically for diesels?
I've heard from my mechanic that there's a first gen in my town that's hauled canopies it's entire life (not nearly as heavy as that guy) and went over a million kilometres with no issues to the motor. Asked about the oil and it was Rotella. I've heard of Rotella being used in high mile motors so that's what I've been using. I switch it out every 5k km, but I might just double that.
My mods are 4" tbe with twister muffler, thd fuel pin, and 366 spring in my '91 non-ic 5 speed W250.
Thanks for sharing valuable information. However, I go by oil analysis report and found the best oil and its the only oil that can give me lowest possible wear metal numbers one single oil and filter in 13 months city driving.
I run Shell Rotella T6 5w40 & Purolator L45335 filter on my 5.9L 24V Cummins. I've had 0 oil related issues at 150k miles and it's still see-through when I change at 7k miles. I don't run fuel additives. Just change your fuel filter every 2 oil changes and you'll be fine. The money you spend on Lucas after so many miles can go to a better fuel filter or a bypass oil filter setup.
