Engine oil VALVOLINE or OEM FORD

You’ll be fine. I’ve used Valvoline for years over various cars. It’s more just making sure you know what oil to ask for.

I dont know but i do know the valvoline restore and protect oil has helped my 330k mile engine feel like new.

I have a 2007 Explorer with 161,000 miles on it. Just recently switched from Castrol to Valvoline Restore and Protect. I'm not sure why I haven't heard of it sooner, but from what I've heard, it's really good at removing sludge and varnish that forms in high mileage engines.

I change the oil using Valvoline for the very first time. I pulled a valve cover in the next oil change and was shocked again! The heads were completely void of sludge! That’s when I became a dedicated Valvoline user and have used it ever since. I run it in everything from Porsches, Corvettes, I use the VR1 in my flat tapped engines and have never had a problem in well over 50 years. Just change the oil and filter every 3k miles or so and the inside of the engine will be clean as new.

I would do several short interval (like 1k honestly) with valvoline restore and protect.

Change your oil with Valvoline restore Cummins oil I think I used 10w30. It will help... I had a a4 with 130k miles and I did this 4 times it cut my consumption down to a minimal amount

Same issue, same engine. Switch to specifically Valvoline protect and restore 5w30, run a bottle of Berrymans B12 cleaner thru the gas tank before your oil change. I did this and saw improvements.

Could be a spark plug, ignition coil, injector or low compression.

I have a 19 xlt. Love it except for the oil issue.

I used that once years ago in my 2011 Limited on Stage 2. What a waste of money.
