Restore & Protect Full Synthetic 5W-30 Motor Oil 1 QT

Too soon to say whether its cleaning inside as it suggests 4 oil changes to show the effect. But the oil definitely made the engine noticeably quieter, smoother, and reduced the fluctuating revs I had due to the sludge (which I am hoping to clean by this oil). So its definitely effective in getting control of the internal lubrication requirements.

Restore & Protect really does what the name promises I picked up Valvoline Restore & Protect Full Synthetic 0W-20 as part of my regular oil change routine, and after running it for a bit, I’m genuinely impressed. This oil pours cleanly, doesn’t feel overly thin or watery, and immediately gave me a smoother, quieter startup compared to the oil I drained out. Cold starts are noticeably calmer, and the engine just feels happier overall. What stood out to me most is how smooth things feel after a few hundred miles. Throttle response feels more consistent, idle is steadier, and there’s a subtle reduction in engine noise that you don’t always get from standard full synthetics. I’m not expecting miracles from motor oil alone, but this one clearly seems to be doing something beneficial internally. I also like that this is aimed at both newer engines and higher-mileage vehicles. It gives peace of mind knowing it’s designed to actively clean deposits over time while still meeting all the modern specs for today’s engines. I paired it with a quality oil filter and have had zero issues with oil consumption or leaks. Things to keep in mind: this is a bit more expensive than basic full synthetics when not on sale, so it may not be necessary if you’re already running a very clean, low-mileage engine. Also, the “restore” benefits are meant to happen over multiple oil changes, not instantly. Bottom line: A high-quality full synthetic that delivers smooth performance, quieter operation, and long-term engine cleanliness. Well worth it if you want extra protection and plan to keep your vehicle for the long haul.

My wife's car had greatly reduced oil consumption after 500 miles of the oil change. About 1 quart every 1,000 miles. After 500 miles there wasn't any noticeable oil consumption. Good stuff.

This newer Valvoline Restore & Protect is an awesome Full synthetic oil that cleans out sludge, carbon and the oil passages. The value is great for many vehicles that have not been taken well care of. The price is right on par with other Valvoline products and its lower quality competitors. I use this in a half dozen vehicles, even though they have been taken great care of. You can use it constantly going forward or 4-6 oil changes to clean up an engine. The VOA's show great additive and wear packages. It is API SP certified, but I believe SN Plus previously is a better API rating. Functionally, I can guarantee it works because I cut open my oil filters and have found carbon in the pleats. I will continue adding friends and families' vehicles into this product line.

Valvoline Restore & Protect Oil has worked very well and appears to have the cleaning action that is advertised. Great product.

This oil absolutely is awesome, this stuff cleans out varnish and carbon but not so tough that it needs flushed out. Use it and keep using it...
