Synthetics in a diesel pusher

Where pure synthetics shine is in extreme cold temps, like -20F ! Amazing how fast a engine will crank with synthetic oil at that temp !

API Charges an oil company to be "certified". Amzoil for years was never API certified.

There was (is?) a snake oil salesman in OH that was selling his custom blended oil. A few of us figured out exactly what he was selling through individual conversations. He was buying penzoil full synthetic, adding a moly product, and selling it as a product that changed the molecular structure of the engine. He was good, really really good :)

Such is life :)

AMZ/OIL Severe Gear is one of the highest rated lubes out there.

Over 400k on my 86 C20 still in good shape. Dana 70 in my 98 2500 RAM looked perfect at 300k when I broke a pinion gear tooth doing a 30# boost launch in 4wd. I can go on and on with excellent results using AMS/OIL products.

Mex, Is this https://lelubricants.com/lubricants.html the link?

DANG! Thank You! YES. I think their grease and especially their gear oil to be near miraculously better than any other. CHEVRON RED GREASE also is the only competition to Almagard red grease.

Grease ONCE, immerse in salt water trailer use for ten years and then wonder why you were so stupid about good grease, is the only negative with both these greases. Wheel bearing re-packs last virtually forever. Do a teardown after six years of use, and feel self conscious about wasting time. My kind of product.

LE's AMASOL 607 gear lube dramatically lessens seal leakage. Weeping stops. The lube cannot churn into WATER POISONED chocolate milk. Impossible to touch bare gears and bearings.

And I have had 180 degree experience with AMZOIL. My opinion is it is over-hyped utter garbage. Amzoil without question destroyed gear sets and bearings in-my-face. It hurts me to even spell the name.

I get a kick, and a good laugh, every time I read a post about synthetics and Dino oil. I never realized there were that many experts about motor oil. Most are personal opinions with no technical support. Even when a statement is supported by an oil engineer or in writing, it’s still not good enough. Almost as entertaining as the posts that say my truck is better than your truck.

An oil change is the most common and simple maintenance item that can be done on an engine that usually requires at least one tool. With so much experience floating around out there, is it any wonder that everyone is an expert?

It's always amazing to me that simple instructions like, "follow the maintenance schedule in your owners manual and use the recommended fluids" can be interpreted so many different ways.

How many different ways can you re-split a previously split hair?

Amsoil like Golden Spectro is overpriced oil and additives but if you want to blow your money on it, have at it.

You have a better report to show using any 15-40 in a Cummins 6.7 towing a combined 33-35k at a 15k change? If so please show it.

You can thank AMZ/OIL for synthetics in the auto industry.

I'm betting your DP is pre emissions 07 or older. If so AMZ/OIL is one of the few that still offers NON LE 15-40. I have had excellent Blackstone reports running this in my Cummins engines and the LE 15-40 in the newer trucks.

Report from 45k change at 15K interval.
