Owner reviews for engine oil

5k or less with Liquimoly. Just had oil pan and upper timing cover replaced at 123k miles (plastic parts leak/ fail bc of heat cycles) and my timing chain looked like new, and not one spec of metal or debris on the bottom end. Unitronic stage 1+ since 75k miles.

I send an oil sample to Blackstone Labs every single time I change the oil or the dealer changes the oil. As part of that analysis, I pay the few extra bucks for a TBN calculation. On my SQ5 and S3, after running a fill for 10k to 12k, those TBN values always come back greater than 1.0 indicating that there’s still enough remaining additives to continue running that fill for even more miles still.

My local shop in Canada does it for $125 plus tax and uses liqui moly oil.

While any oil can work for your car, the current best option in the market is Pennzoil Ultra.

The same oil goes into all GDI engines at my dealer, which is Shell Helix Ultra SP 0W-20. This is a super expensive, latest spec oil. Oil changes with this oil are done at 9320 miles if turbocharged and 18 640 miles if naturally aspirated.

I have an MX-5 with that engine, Mazda uses Castrol Edge 0w20 but you can use a heavier oil and sime say it reduces wear. The purpose of the 20 weight is fuel economy.

Used zic for several years with no issues. This year lang ako nagpalit ng ibang brand since nagmahal na zic dun sa suking auto supply ko.

I run Amsoil in my 100% in my vehicles and lawn equipment. It’s synthetic, uniform, and has low volatility unlike petroleum based products. Less frequent oil changes.

I’ve been using zic oil for 6 years now. Ok naman I did not experience any issue.

i use valvoline 5w40 ...so those results arent so good?
