Engine oil Shell or Motorex

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!

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.

I switched from Castrol Edge 0W-40 to Shell Helix Ultra 5W-40 on my E46 325Ci and feel it runs a touch better and doesn't burn as much oil. Before I was adding 1L per \~3000km, now maybe 1L per 5-6000km...

First impressions - engine is noticeably quieter and smoother at idle. Engine temps is lower by 1 line. slightly better throttle response. As for fuel consumption, i have to drive more my usual route to know if there is an improvement.

Rotella T6 0W40.

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.
