Camshaft wear protection of Mobil 1?

Fuel.....fire


Yes, but the sequence pics were also dragged out in that comparison, and that's a low-stress roller application where wear isn't an issue regardless. That thread was ridiculous.

A few years ago, Terry Dyson made a post about how Mobil 1 allowed more valvetrain wear than he cared for. I think this was with the SM Mobil 1. Does anyone know if Mobil fixed this problem?

You're making assumptions that:

1. TD had properly correlated camshaft wear with the exclusive use of M1, disregarding other important factors.

2. M1 had a problem.

Ouch. I remember that thread quite well.


That was a fun thread,I remember it well! I bet it's one of the longest and most legendary threads here.

Looks like this is an outtake from it.

OK, not to hi-jack the thread, but this discussion may shed some light on camshaft lubrication. That is often Fe to Fe contact and can be under very high pressure...

https://540ratblog.wordpress.com/ I suggest reading it completely through at least the first half. That testing was to try to resolve camshaft failures which were epidemic a few years back when the ZDDP was being pulled to meet requirements. Turns out that there are other good AW additives and some oils quickly rose to occasion and are top rated .. Synthetics and well refined Dino's too

M1 rates well and is a good oil. The best, well that's debatable... There is better to be had from Motul, but at $19/L it is not cost effective for many folks...

Maxlife Blend is turning out to be quite well rated and received. It is cost effective if you are inclined to go that way

Since I build high performance BBC's with flat tappet cams, I'm very concerned about oils and have been paying close attention to this debate for many years now ...

And there is ongoing evidence that roller bearing roller lifters have been failing at about 5K miles under competition spring pressures. Trunion roller lifters are lasting much longer. But some have been spalling the roller and that takes out the cam lobe surface. Figuring out what the cause is, is not trivial...

Thanks mate.

Except the engine in that thread is a Ford Modular with light springs and roller followers. It is the definition of a low-stress valvetrain.

I don't think the SM version of Mobil 1 was their best, from a historical perspective, but I think their latest oils are among the best. M1 will always be at the top of the list due to XOM's strong R&D and being such huge player in the market.

They were impacted by Katrina a bit and had some temporary formulation issues, but nothing serious.

As much as I hate to admit it buster is right. With the basically unlimited resources Mobil has for research and development they will always be at the top of the heap as far as quality of product is concerned.
Shell too. When you have the kind of money these guys have you can employ a team or teams of scientists,researchers,test mules and so much more. So they will always find the best,cheapest way to achieve a goal,and that cheapness means the consumer isn't paying boutique oil prices for better than boutique oil quality.
So yeah. Mobil and shell will always be on top. When you have the kind of money they do they better.
