Engine oil VALVOLINE or ZIC

No issues at 150k on my 6. I do not worry but do run pea type injector cleaner every 3-5k and use quality oil that helps prevent off gas issues like Mobil 1 and Valvoline

I use Valvoline Restore & Protect, which claims to clean your engine and reduce friction/wear more than any other oil

I use Valvoline Extended Protection Full Synthetic 5W-30.

Very good on engines and your turbo especially (i have a 2014 st3)

I have a 2011 Escape Hybrid 2.5L with about 175,000 kms. I run Valvoline Advanced 0W-20 full synthetic as recommended by my mechanic. I've found it much better on fuel economy in colder weather than the 5W-20 for multi-seasonal use, especially in colder weather regions (I live in BC, Canada).

Been using it for several years already and very popular brand na sya ngayon since anak ni Lucio Tan ang distributor.

Use their X7 if you plan to change oil every 6 months. Use X7000 for yearly changes.

Valvoline Restore & Protect. Its no joke.

I use Valvoline Synpower

I’ve gone down an oil research rabbit hole many a time. There’s been some extensive studies done and besides liqui moly, studies have shown that Valvoline extended protection has some of the best wear-prevention additives and performed among the best in lab samples pulled from used oil.

My current favorite is valvoline 5w30 full synthetic. There are oil analysis of new that show it has a high 100 C viscosity and it has a ton of really good additives.

I personally run the valvoline, seems to be a tad quieter on the valvetrain.
