    Looking for a better alternative to Castrol EDGE 5w40

    Unless you want to do extended drains I would go with whatever is cheapest.

    New GL-4 Oil

    Thanks so much Molakule! By interchangeabiltiy, I mean, if my old Nissan truck specs a 75w-90 GL-4 and I put in a 70w-80 GL-4, am I creating a condition where more wear will occur. Or since they are both GL-4, should the same amount of wear occur reguardless of viscosity? Companies like...

    New GL-4 Oil

    I'm intrigued by this. IE, if two fluids have GL-4 rating, but are much different viscosity, will they offer the same wear protection just at different cost and cold weather shift performance? Intuitively it seems making a 75w-90 GL-4 could cost much less (using lower grade fluid with fewer...

    Best oil for Audi 4.0 twin turbo

    Before the low saps craze, VW 503.01 was the Audi high horsepower turbo spec oil. I believe that spec is still listed on some oil containers today like Castrol 0w-30 and Mobil 1 0w-40.

    Who remembers Green GC 0w-30?

    Haven't been on this site for a long time. I no longer have the '03 Passat V6 that I bought new, but this was the smoothest oil I ever tried in it. Bought a big stash and then sold off a lot of it to folks here. My engine just seemed more quiet and smooth at higher rpm's with this stuff...

    Sig Sauer P320 will fire if dropped

    Making the trigger lighter just means it will still fire when dropped, just from a greater height. So don't climb any ladders or trees.

    How does Porsche A40 spec differ from VW502?

    From that Lubrizol site, VW 504 looks the most impressive to me.

    75W-85 vs 75W-90 for MTF?

    My take, which is probably wrong, is that today the base oils are so good that it no longer requires a 90w oil to achieve the GL-4 rating. When GL-4 was blended with group 1 many years ago, 90w was probably needed. Back then a 75w-90 would shear down faster than today. I may try to call...

    75W-85 vs 75W-90 for MTF?

    <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Oro_O</div><div class="ubbcode-body">So, does anyone have a place to get some reasonably priced GL-4 75w-90? I need quite a few quarts of it, and at $15/each it seems a bit pricey. Or is that just the going rate? I...

    75W-85 vs 75W-90 for MTF?

    Got it, thanks Molakule!

    75W-85 vs 75W-90 for MTF?

    Just curious, but since a gl-4 has half the ep additive of a gl-5, couldn't a 1:1 mixture of gl-5 gear oil and diesel engine oil of the same weight be mixed to create a gl-4?

    BMW LL01 alternate oils

    The 1.8T's were originally on 10k oci's, and along with a low sump capacity, many were using non synthetic oil.
