^Oh, ok. Sorry. I personally haven’t seen that logic touted in a while.

Yep, always find it funny when people go on about the longevity of diesel engines.

Maybe if you are running the carney circuit putting 50k miles per year on a truck towing heavy but not many RVers will get anywhere close to wearing an engine out.

50yrs ago, when gas engines were good for maybe 100k miles, a diesel held a durability advantage but modern diesel engines are complex beasts with plenty of ancillary parts that can fail.

And double the torque of a gas motor. It's all in what you want or need.

I always find it funny when folks who have gassers try to talk schitt about diesels! LOL

If you are towing heavy and need the extra tow rating, sure get a diesel but that wasn't the point.

People go on and on about the longevity of diesel engines and in the modern world, a vehicle typically wears out before the engine does (gas or diesel).

I notice many brands now offer standard 48 months or 50K miles ... and some even 84 months and 70K miles on the power train. Power trains are pretty solid now if you maintain it - it's the electronics and other equipment that wears out quicker.

What’s amzoil? I was interested in looking up information on it and all I can find online is amsoil.

AMZ/OIL is how the Company started out in the early 70's. My Dad was the first dealer in WA State around 1973. I have used their products since.

PENNZOIL did not like the logo as they said it was too close to theirs. Guess what they had bigger Lawyers. So they changed their logo to AMS/OIL but the "S" looks like a "Z".

Quality 100% synthetic products.

If I was going to try to get a gazillion miles on an engine I might want the best fuel filtration and water separator I could find and I'd probably delete the emission equipment the first time it gave trouble ... if not the day after getting the truck home.

88k my emission system is working as it should. Come February when my MaxCare warranty expires my truck will be deleted the first time the system gives me trouble.

My Son deleted his 15 RAM a couple years ago and has been great. He has done Blackstone oil analysis at 22k running AMZ/OIL 15/40 diesel marine non LE with them telling him to go longer.

The only 2019+ (not even a handful of) hyd lifter failures had documentation that they had run 15/40 instead of the approved oil weights.

Not sure I buy the reasoning for no 15-40, fwiw.
May leave a film or buildup? That’s pretty laughable.
And too tight of tolerances? Again seems like bunk unless talking very cold weather.
My opinion is based on historical “requirements” and how they seem to vary so much brand to brand, year to year, engine to engine.
That and hydraulic lifters aren’t magical. I’ve run 15-40 in many Hyd lifter engines including a couple that “required” 0w40. 150k miles later it ran fine and didn’t burn any oil, leak, make noise or any lack of performance.
But am interested in a better explanation of the requirement as all I’ve found is very vague articles. As always Icbw.

This document is craapp!

If your using 5W40 oil it has to be API CJ4 oil. Good luck finding that.

As for 15W40 causing deposits on the lifters is also craapp. You can install 15W40 on a brand new cummins on the first oil change, start the engine and the thing starts knocking immediately.
