Note: you can always use a 5W50 grade, if you're concerned about cold-start flow, though you won't be compromising anything by using Mobil 1 15W50 synthetic year-round in Ireland - just as long as temps stay above 20 degrees f or so.

Same with the S50 - you want at least a 50 weight oil in there. I'd recommend Mobil 1 15W50.

I'd seriously recommend Mobil 1 15W50. If you're on the track, you should be using a 50 weight (at LOWEST a 40 weight grade) oil in an M50 - M54 engine. 5W30 used on an E36 track car is an absolute sin - an absurdity to be frank. Don't take the Oil 101 low-viscosity oil doctrine as gospel -...

Just asking out of curiosity. Engine design interests me greatly for some reason. And, I agree those classic BMW inline 6 engines will go forever. Everything else will go before the engines ever do...

I appreciate the response, but are you certain or speculating? I know your 735i features an M30, yet the M30 was designed in the late-'60s and M20 in the '70s - just want to make sure if that fits modern designation. What year did "modern" era designation begin roughly? Thanks!

Can someone please confirm if the classic BMW engines (M20, M30, or M50) feature a full force-fed oiling system? A full force-fed system requires oil passages in the rods. Full Force-fed System: Partially Force-fed System:

Thanks for all the great posts, everyone. Much appreciated.

Hi, all. I have a general question about the dynamics of a given liter size in different cylinder number engines and the power that can be produced in both 6 and 4 cylinder engine designs, which are both naturally aspirated, both feature DOHC 4 valve per cyl, and both are high compression: A...

Thanks, Stevie and Speedy! Btw, all, I'm not saying either contention is neccessarily the most accurate. I just wanted to put this out into the best oil forum on the internet and see the various opinions and what would be made of it. I have no strong bias either way at this point, so I am going...

Hi, all. I am new to the forum,yet I have read A LOT of the posts here by various posters and A.E. Haas in particular. In Hass' Motor Oil lessons 101 thru 201 http://www.bobistheoilguy.com/aehaas/ his general opinion is overall thinner viscosities are what cars will thrive on - always looking to...
