Owner reviews for engine oil

In my 2020 A6 I had aral oil and it consumed 1l of oil in 15k km. Then I used castrol LL and now it does not consume a drop at all.

I like to use Castrol Edge Racing with the 278cc HPE2, made a big difference to running temps, top speed and effiviency.

In my experience of trying many different oils, what I think are the best, as far as the engine running cool and smooth shifting are: 1. Redline 15w50

I noticed a massive difference switching from 0w-30 to Mobil 1 FS 5w-40 in my NG 93. Engine sounded better, burned WAY less oil, and no noticeable fuel economy or power difference. I also used Ceratec a few times and that made it feel smoother.

First oil change after filling with T-6 on my 2002 Saab 9-3 (that didn't have a kit on it) I bought with 130k miles on it was really black, almost a bit sludgy. Next few oil changes quickly got better as the detergent broke down sludge in the top end and cleaned the motor up.

Ran quieter on 5-40 heavy duty diesel Mobil 1

Felt more powerful, but that may have been a perception from quieter and smoother power. Others on Saabnet reported the same.

If you're oil change is specified for longer, buy Mobil 1 in the correct spec grade and change it then, you will save money and use less, which will keep your cash in your pocket not the oil industry's.

2013 Volvo XC 90. Owned since new, only used Penzoil Euro L formulation, all synthetic, 10W-30 and 143K miles later I had to get rid of her because I left the country. No engine issues at all.

I have, hard to tell the difference with these engines. I’ve got 36k on my LZO, and have used the ESP on two oil changes. But again it seems more expensive the AC Delco and I’m not sure what you are gaining

I opted for 10W-40 full synthetic oil (Yacco 1000 MVX 4T). Post-change, I've encountered a couple of issues: Reduced Power: There is a noticeable loss of torque. White Smoke: White smoke is appearing from the motorcycle, but it's not emanating from the exhaust.
