What oil?

[174bpm]

As a few have noted in here already, FCP changed the game for me. I've been using Liqui Moly 10W-60 for a few years now with no problems. With FCP's lifetime replacement policy can't imagine using anything else. They do sell the BMW 10w-60 I think too.

I use Ravenol 10w60 in the summer (and on track). I like Castrol 0w40 A3/B4 in the winter. No data beyond what's been posted - just arbitrary preference.

I'm adding nothing to this thread but I use liquid moly 10w-60 and have been for the last 30k miles with no issues. It's free from FCP euro too.

Olive for light sauteing
canola for frying

...and Hawaiian Tropic for a deep dark all over tan.

Always Redline 5w-50 for me. Oil changes every 3-5k as it shears down a bit faster.

Spoke/texted with a friend having his S54 bearings replaced in his race car as we speak. He has WPC bearings and has been running Total Quartz 10W-60 synthetic racing oil with LiquiMoly Cera Tec (https://products.liqui-moly.us/cera-tec-1.html) . This will be fun to compare if the LiquiMoly additive actually helped when I tear down my motor.

If you had a failure within 5000 miles, it's not the most recent oil change where the bulk of the damage was done. Those bearings were going to pop no matter what you put in there at that point.

I'm going to pull the 5 out that aren't welded to the crank and check them in the next week or two. I definitely want to see how bad they are. The engine I just bought had bearings that were in such good condition, I would've put them back if I hadn't bought bearings already. It

FCP Euro completely changes the game for oil. After just 1 lifetime exchange, the effective price drops so low that there's no way anything from any other vendor could possibly be worth the money. Like, there's no way for an engine oil to extend the life of an engine by enough to offset the price difference.

BMW Twinpower 10w60. The lifetime replacement through fcpeuro keeps me consistent.

I installed my oil wrong??? Bearings were put in by BMW in 2006.

If your bearings went out after 5k then I'm more inclined to think that there was an improper install. Of course, there's no way to prove it and you're being biased toward an oil that many others are using with no complications and without using additional additives.

Redline 15w-50 per Bimmerworld's recommendation

[DESMDR3]

I switched from motul 10w60 to redline 5w50. ~3k between oil changes. I’m on my second oil change with the 5w50, I forgot to sample the first time lol
