jas81172 0 Report post Posted November 29, 2009 i just purchased a 1988 320i e30 a year ago and would just like to know if anybody here using valvoline synthetic 5w40 as the engine oil for the car. i'm planning to try using it for my next oil change. it is pretty much available and cheaper than the other brands but would like to know it is worth a try?tks.

bravo 35 Report post Posted November 29, 2009 Valvoline has a good reputation, but I'm not sure if 5W is a bit low for an older car. Others may wish to coment. I use a 15W40. Quote Share this post Link to post Share on other sites
Forrest 35 Report post Posted November 29, 2009 I agree with Bravo, does seem far to thin for a 20/25 year old car. I use 15w40 also. Quote Share this post Link to post Share on other sites

I use a 15W40. +1 or a 10w40 semi synthetic, but no thinner than that on the older motors Quote Share this post Link to post Share on other sites

oscar90 0 Report post Posted November 29, 2009 Temp sits about half, a little less maybe, in all the BMWs we've got, use magnatec in them all. got a E30, E36 and E39, so i'd guess its normal for it to be 1/2 way on the gauge Quote Share this post Link to post Share on other sites

Talking out his bum. You will not notice any temperature changes on an M20 by changing oil viscosity. And the factory temp gage is not something you can measure any changes from. I run 10w40 Elf in my race car. But the motor is new and it gets changed out every couple of race meets. Ran 15w40 in my old 325i. (Forests Car). It is also a good idea to stick to one viscosity rather than changing every oil change. Quote Share this post Link to post Share on other sites

Would make negligible gains if any. The theory behind them is fairly sound, but in practice, they make next to no difference. Despite what some will say, the intake path for m20's is fairly efficient based on some comparative dyno testing at Hi Velocity. Quote Share this post Link to post Share on other sites
