Engine oil VALVOLINE or RAVENOL

Both of my Guzzis ran better on Valvoline. This is if you’re in USA

I'm using Valvoline 0W-20 Restore and Protect, changing every 4,000 miles. '23 OBW, 56,000 miles. FYI, I did an oil analysis at my last oil change. Wear numbers were excellent, less than 1.5 ppm/1,000 miles. 3 iron, 2 aluminum, 1 copper over 4,128 miles. Fuel dilution was HIGH though, at 4.3%. They expect 1.5- 1.8% for direct injection turbos. According to the Motor Oil Geek, less than 5ppm/1,000 miles is considered good. I do a fair number of short trips, but also some longer runs. I'm going to go to max of 4,000 miles due to the gas dilution.

I’ve used it, no complaints.

One oil that seems to work from all the videos I've watched for cleaning varnish is the Valvoline Restore and Protect.

I use this on my Hyundai Elantra for the past 100k miles ... It's already at 200k and the engine still feels new ... I use Valvoline for everything including power steering ... Valvoline syn blend is a great oil option ...

Valvoline protect and restore has more detergents than any other I believe to clean out thew gunk. I've been running it in my car for 3 oil changes now.

I've seen lots of videos showing the Valvoline restore and protect oil helping to clean engines. If you go that route I'd recommend replacing the oil filter after 500 miles then again at 2500 miles to keep the filters new for any gunk that gets freed up.

Use Valvoline Restore and Protect oil if possible

Legit. Worst case scenario it doesn't do anything, but I've seen some improvement in my Cadillac ELR. Engine is quieter and lots of sludge was removed. But fwiw lots still remains and the varnish is basically untouched.

I do believe that Valvoline R and R can cause oil leaks. I have noticed that in a couple of cars.
