Engine oil Shell or Lucas

I've never seen T6 in 15-40. It's always 5-40.

Rotella is the best you don’t even need the synthetic. I run it in my 6 bolt 4G63 with 222,000 miles on it pushing 400 wheel horsepower and I’ve been a truck driver for 29 years it’s the industry standard????????

Rotella T6 ftw! I swapped my F800GS' oil to this and HifloFiltro filters years ago and have had zero issues. ~$30 for a full change compaired to BMW's asking price of $23/quart (straight highway robbery) and $20/filter so it was a no brainer saving almost $60/change

I use Shell Ultra Helix 0W-30 but I mean I drive diesel idk how it looks like for n20 or b48 engines

Brings me back to my WRX days, we all used to run Rotella T6 because it burned less oil thru our gigantic subaru ring gaps.

I always used Rotella 5w30 gas truck oil designed for “All Mileage” in my 2005 Nissan Frontier with 95k but it’s been discontinued. I really liked this oil as it seemed to be thicker and remained viscous for longer compared to others. My favorite part about it? NO LEAKS!

Right now I have some Lucas High Performance, but the brand is relatively immaterial to me. As long as it's a reputable brand and it meets the spec in the manual.

Shell Rotella T6 5w-40 in my 09 e90 335d (m57)

Supposedly should be changed every 13k miles but I do 7500 to hopefully help extend the life of the timing chain.

I’ve a 01 330ci with 284kms on it and I’ve been running Rotella 5w-40 T6 for a few years and it’s been really good. Keeps it good and clean for 10k change intervals. I probably end up adding 2-3L over that time, which was a vast improvement from when I got the car 30k ago.

G60 Carat said: Speaking of Rotella, Here's a personal observation of mine. My beater Saturn 1.9 has a lifter tick (not fixing it, don't care), so I just put in Rotella T, and it quiets it up a bunch! But last oil change I just used the 20w50 I had on the shelf for the VW, since it's in pieces anyways. Despite the heavier oil, the lifter tick is louder with 20w50 that it was with 15w40 Diesel oil.
