What oil?

[r4dr]

I can't wait to fill my engine. Sadly I need 6.5L and used about half already during lubing an engine that was sitting for a while. When the oil filter housing is removed, BMW calls for an extra liter and I definitely saw why when I rotated my engine on the stand. Oil somehow kept coming out. It was spawning out of thin air it almost seemed. I feel good using Castrol TWS because so many have been using it. Hopefully we didn't buy knock off oil...

I don't think we did. Amazon has a huge fakes problem but usually "sold by Amazon" directly is ok. And it's not like the price was too good to be true.

I would be genuinely curious how an engine with bulletproofed rod bearings runs on 0W-40 longterm. Not curious enough to do it myself though.

Just did an oil change today with $9/L Castrol 10W-60 from Amazon.

Used nothing but BMW 10w60. Definitely will be ordering more from FCP Euro!

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

...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.
