1990 Alpina B10 Bi-Turbo (based on e34 535i). Dino oil.

I like to use synthetic, but since i work at a shop that i get free oil at I use dino, but I change it once a week, regardless of the mileage. I could put 2 or 200, still once a week. My oil looks brand new every time I change it. And I change the filter every 5000

I'm on dino right now in the 540i. I will eventually switch, but am going to wait until all my other issues are ironned out. Don't want to risk starting an oil leak when I already have a laundry list of things to do...

Synthetic, works well in the engine, not so good if the lid comes off the bottle in the boot (trunk) though..., on a brighter note, at least my carpet doesn't squeak.

i may switch to synthetic sooner or later...i just get a better price on dino from my indy ($1 a quart!)

I use Dino because its what my dad buys for me. Free oil > Expensive oil. I will switch to synthetic when i start buying it myself.

215,000 miles and doesn't use oil between changes, so synthetic is the only one for me. I'm shooting for 300 k without major engine work.

I use dino oil because it's a I know. All the horror stories of switching to synthetic scare me. I could still be convinced, though, maybe...

I use synthetic in my other car which had only 90,000km on the clock when I acquired it (versus 215,000km on the BMW). I've been using synthetic in that car since I got it and it runs beautifully.
