Owner reviews for engine oil

Valvoline MaxLife 10W40. Made specifically for older engines with high mileage.

I got a 1.5dci kangoo - and I kept seeing RN720 5w-30. So ordered liqui moly top tech 4400 5w-30 as that was specific to renaults.

Have to flush out the old oil as its been sitting for a year (using liqui moly engine flush) and will see how the new oil runs.

I recommend Royal purple XPR, or amsoil zRod.

I've used Penzoil Euro, Motul, Liqui Moly new gen all 5w-40 except Mobil 1 ESP at 5w30. I did like liqui moly the best but it's probably my imagination from the fancy green oil\ud83d\ude05

My Tiguan and Passat all function perfectly with Mobil1 5W40, and I have used this oil for 15 years.

Try 10w40 after a engine oil flush use liqui moly engine flush. If the 10w40 works fine take it down tk 10w30 then 5w30. I am using 5w30 on a reborn.

My dealership usually overfills my car and I do not think they use Toyota 0w-16 based on oil tests I have done. I do my own changes and switched from Toyota 0w-16 to Mobil 0w-16 and landed on Pennzoil presently and going forward.

I personally don't use 0W-20, and instead I use Liquimoly Liechtlauf 5W-30 oil, and I change it every 5,000 miles.

Currently on valvoline and it does seem good, not sure if it's better than the elf in the short run but long run could tell different results.

If you have ever rebuilt an engine that used Pennzoil, you would never use it again. The top of the head will be covered in carbon.
