Engine oil VALVOLINE or AMSOIL

Im currently using it in my car (2017 Ford Fusion 2.0 Ecoboost), and just made a long road trip around 2k miles in the summer heat, some around 100 degrees. The oil looks fine, not really dirty in my case.

My prius went from burning a quart every 1000 miles to almost no consumption after 2 changes with r and p. The oil was so disgustingly dirty the first change which i did at 3k instead of 5k. It definitely cleans your engine out.

I\u2019ve been running Amsoil signature 0w-20 in my FL5 for about 5k miles now. No track driving, just a mixture of city/highway. Some spirited pulls and rowing through the gears but mostly normal driving. Car is stock aside from PRL intake and custom tune. Had Blackstone do an oil analysis after the first 3k miles and all was well and below the average for all wear metals. I\u2019m in Florida so pretty hot climate overall. Very happy with the oil and will continue to use it at that viscosity

Y'all might call me a heretic for running Valvoline restore and protect 5w30 in my 4.0T.

Any oil that meets API SP and is the right viscosity grade more than likely is at least as good as the oils specified by the OEMs.

I don't know what it's doing inside my engine but I just did my 2nd oil change with R&P and noticed my dipstick looks new now. No signs of any varnish, just shiny clean metal.

Extra info, I have seen some stuff about valvoline. Engine looks pretty clean inside after they ran valvoline restore and protect.

Change your oil to Valvoline Restore and Protect 5W-30! Change every 3000 miles, filter too!!!!!

Valvoline is the best and bang for the buck for me.

I’m running basic conventional 10-30 Valvoline. Oil changes every 3500 miles. 185K miles, track if 5x a year

im actually running that oil right now... I hate it tbh. 3,100 on the oil and it has allowed excess engine noise since day one, SUPER harsh cold starts, and now its burning through faster than the catrol I ran when I first got the car. a WHOLE QUART over 750 miles. the oil is thinner than piss going in, and it just doesnt stand up to what my engine can put out like Shell Rotella T6 has been doing...
