Oil for the e30 this winter

oldskool3 · 12-11-2009, 04:01 PM

Well my complete lack of funds for a winter beater has led to me driving the e30 this winter despite being very fearful of the rust that will inevitably develop. Anyway, I just got my new diff. put in by Raph and I think she deserves an oil change. What oil do you guys recommend. I was thinking 10w30 but I don't know if that will be too thick. Anyway let me know what you guys suggest for our -30+ winter days.

I used to run 10w40.

I don't think anything can be too thick for an e30

In the engine or the diff?

Thinner is going to be better for startups, I used to run either 5w30 or 10w30

I was asking about engine oil. I think I will probably end up running 10w30.

10w30 is fine...you aren't racing the damned thing!!! m20 is virtually indestructible...

For an Ottawa winter use 5w-30 if you're using dino oil. Don't use anything thicker Please please please. the cold mornings the engine will thank you. Most engine wear occurs at cold start, the faster it flows when cold the less wear there will be, and the longer the engine will last.

BTW a 10w-30 has the same viscosity as a 5w-30 when hot. So using a 10w-30 during the winter is just pointless, because you're ending up with less protection when the engine needs it most, at the cold end of the scale. Also during the dead of winter, the oil will not reach the temps stipulated by the second viscosity rating (210f), meaning the lower end becomes much more important. (I've done physical measurements on this). So stick with a 5w-30.
