which engine oil for winter... newbie ?

[forevernewbie]

I got a 97 M3 with 92 Kmiles two months ago.
I am having fun with car so far (except when it snowed here yesterday and I was on summer tires )

I am planning do a engine oil change my self. I looked at E36m3faq.pdf at at eurospeed.org
which recommends 15W40. But doesn't recommend anything specific for winter. I am driving this car in detroit winter.

I am planning on putting 5W30. I am not going synthetic becos of high mileage on this car. It will be regular Castrol oil.

Any recommendation on type and brand of oil for winter?
I am planning on putting 7 qts of oil.

I know there is oil section in this forum. But I get confused with so much detail and I see synthetic on that section most of the time..

Thanks

A lot of people here switch from mobil1 15w50 (summer) to mobil1 0w40 for winter.

I'm doing the same within the month. Just need it to stop raining when i'm free.

that car should have come from the factory with synthetic, so I dunno why you would say you don't want to "switch" to synthetic...

No e36 m didn't come with synthetic back then. Most have switched over though.

does anyone know if 10w-30 would be could for canadian winters?

my brother is taking his S52 M coupe to move to canada and we want to switch to lighter weight oil.

Pro-Line 10w30 works great in the winter and it's cheap!

I run Mobil 1 10w-30 all year around with no problems.

97s did not come factory fill with synthetic.

Anything at or under a 10W cold will be fine. 5W40 Amsoil would be expensive but you could run it year round.

Frist off, hi and welcome. Next you could rtfm, but since there are a lot of guys with nothing better to do just sitting at home logged on to this site, it's just easier for you to ask here.
