Doesn't look too bad. The only thing that caught my eye was the fact that this oil is now a high 50 wt. Still more than enough to continue protecting.

I have a regular 2003 330i Would it be ok to try this oil in my engine instead of the regular 5w30?

I thought someone (maybe Dr T) had posted a VOA of this oil, but I couldn't find it.

Considering 240 Autocross runs and spirited driving I'd say this is an excellent report. To be picky, I wish it had held a higher flashpoint and stayed in grade, but given the demands placed upon this oil, that probably IS JUST BEING PICKY.

I don't recall him posting one, he's never done a VOA or UOA yet.

More and more we're seeing some good numbers from thicker oils, it sure makes you stop and think.

I've found another UOA for this oil: TWS 10W-60 in '03 M3 but no VOA.

Go tell that to Buster, Pat....he'll flip.
Oh heavens, I hope he doesn't read this.

Anyway, I agree with you Pat....my next OCI will be either 50/50 10W30/15W50 or all 15W50 M1 depending on the weather. We are already getting some cold fronts here in SA, TX.

No, I"m not going to flip. Great report. Hey, if I turn out to be wrong, thats fine. I'd like to get to the bottom of this debate anyway. Plus it will help me determine whether or not I should use a heavier oil..

Dr. T · Sep 20, 2003

You're right I've never posted a UOA or VOA...but promise to once I clean the crap out of my engine (from the BMW 5-30) ie. the next interval.

And yes, you could safely use it in you standard 330...as the Australian website says "safe to use in all engines"...

Here is a formula Buster;
Thicker for summer and extreme driving....thinner for winter.
Speaking of extreme driving, I would not be surprised if Ford's plan of using 5W-20, even on their heavy duty trucks backfires one day.....There is no way I would put anything thinner than 5w30 unless it's extreme winter.

No hard feelings Buster......I come here seeking for the best product for my vehicles...not to pick a fight.

It's all good. I'm not fond of 20wts either, only Redline's and Mobil's bc they contain a strong base oil with a good amount of EP/AW additives. A dino 20wt? NO thanks.

Let me be clear too, I"m not against thicker oils. I'm just not convinced you need one for every engine/car out there.

It lists for $8.95, BMW P/N 07 51 0 009 40.
I've heard that some dealerships are charging even $12 for it so beware. It's still cheaper than in Europe where it costs around $16 Euro/liter

It averages around $9.00 per quart, though I have heard of some dealers charging as much as $15.00.

Hmmm...maybe I should try this is my Chrysler.
