Owner reviews for engine oil

Shifting feels smoother, I stopped feeling the sensation that on high revs the motorbike stopped accelerating (clutch slippage???) and I finally find neutral easy at stops, sometimes I have to rev it a little with the clutch pulled, also I don’t feel the kick when clutch engaged

We have been using T6 in all our race engines for over 10 years

Great stuff, wet clutch wear is good and the engines look great inside when we tear them down for rebuilds

I have used it for years in motorcycles. I have tried other super expensive oils and some of them shift a little nicer for longer, like Liquid Moly. But, T6 is a very high quality oil and I still use it and change it when shifting feels clunkier or 5k miles whichever comes first.

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????????

I do all my own work and the oil changes are either 10k miles or yearly, usually yearly. I'm not too concerned about the exact date but basically every spring the cars get an oil change, air filter and cabin air filter.

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 go to a local Toyota/Lexus specialist here in San Diego. They use Kendall liquid titanium and it cost me about $75.

Not going to lie. I use Walmart auto for my oil changes. If you synthetic premium you can pick your own oil, I use Mobil one.

My wife drove her 2008 Passat 2 miles per day for six years. As you can imagine, during these very short drives in winter, the oil became diluted - this was born from sever UOAs. So, I changed the oil every 1,500 miles and the oil and filter every 3,000 miles. Over-kill perhaps but based upon my personal expectations, worth the time and money. We used Mobil 1 0W40....which sheared to a 0W30 fairly quickly and stabilized.
