Oil?!

Steve30 · 03-10-2010, 06:58 PM

I ran royal purple 5W30 last summer but noticed some lifter tick after aggressive driving so I want to change to a heavier oil. I'm leaning towards an xxW40 oil (possible lubro moly 10W40) but please share your opinions.

why not just stick with what is recommended and change more frequently?

I wanted something that's a little heaver than what BMW recommends (5W30) and a full synthetic, not a cracked oil. I think 30 is just a bit too thin. I ended up getting some 5W40, we'll see how that goes.

Run something with BMW LL approval, like Castrol 5W-40 or Mobil1 0W-40.

Thanks Rich, I'll check it out for when I do my next oil change.

BMW changed their mind ... it now recommends 20w50 in the summer. Personally, we run the 10w60 TWS or the 20w50 amsoil 2000 series.

Definitely not, especially if you like to rev the bastard

richie_s999 · 03-29-2010, 03:01 PM

First number is the weight once warmed up it has no bearing and viscosity comes into play. That's how the oil is under heat and pressure.

I'm one of the few guys that runs BMW 15W40 because my car seems like it a lot. No tick and no pinging.

You might want to check your plugs too if you have excessive tick.

Steve30 · 03-30-2010, 01:22 AM

yea, the car is getting a full tune up this Saturday when I pull it out of the garage!

Yup good choice as well. The old Mobil 1 15w50 (or 15w40?) was a great oil. I think the new long-life is a decent synthetic these days, and relatively cheap.

We actually use diesel oil in the race cars (15w40) for engine break in and initial run in, then switch to teh amsoil or TWS.
