VALVOLINE Engine oil

NOW, my last oil change I did 2 weeks ago I used Valvoline Restore & Protect after using various Mobil1 & Valvoline high mileage oils. And so far after checking my dipstick today the oil level is still at the top of the fill line. I’m not guaranteeing that this oil is in fact revolutionary but I have noticed significant loss in oil consumption & a more quiet engine bay.

Pros: loss in oil consumption, quiet engine

I work in the automotive industry; and by far, Liqui Molly, Motul, and Total exceed Mobil 1. Mobil 1 has the recognition and they worked hard at marketing for many years. Independent German studies conclude that they are 3rd place at best when it comes to \"good quality\" oils.

Pros: good quality oils
Cons: 3rd place at best
Vehicle: Volkswagen

I have been running Mobil 1 0w-40 since new with over 50k miles on different Big turbo(80k total miles) setups and always replacing seals and gaskets due to oil leaks(its some really thin oil).

Cons: oil leaks, too thin
Mileage: 80467 km
