Whats your weight? (fossil oil)

[Sirius600]

Since I'm considering switching to synthetic oil, I think it's suiting to start a poll on oil weight. This is for regular oil users ONLY.

Please include your location and the average temperature where you drive.

I'm running Mobil-1 15-50 in my 3.2. I don't remember what I was running in my 1.9, but I think it was 15-40.

I'm in CT (usually) but the BMW is never driven in winter.

Mobil 10-40 in the M44

[2ndBimmer]

I use Castrol 20w50 in the summer (85º), 10w40 in the winter (30º).

[CyPRus]

Just been going according to the manuals that came with my '95. Recommends 15-40 for summer and probably switch to I think it's 5-30 for winter. Probably wrong so I'll be double checking. Supertech is unfortunately what is on the shelves in my area. Not a lot of 15-40 castrol in my area otherwise I'd be using it. Probably order some for my next oil change through napa or something.

I only use Mobil 1 RED top I think it is 15w50. douring the summer the oil gets pretty hot and lacks of viscosity. heavier weight keeps the compression going.

20W50 I live in Indiana right now it is 0 degrees, but usually during winter it is around freezing or a little above.
