For those interested here's a video on 4k miles using VRP by DIYAutoworksNG. I believe its a Gen9 4 cylinder Accord. Skip to 1;50 if in a rush. Compression up in all 4 cylinders.
Valvoline says to change the oil with Restore & Protect four times for it to do its job. (4 times in typical oil change mileage intervals not drain & fills)Interesting, I never thought to do a pressure test.
I'm on the first VRP oil change, about 5,000 miles in to it. I have noticed less oil consumption so far.
I did some digging online and a lot of reviews say your oil filter will get clogged up so you need to check it after 500-1000 miles (which i think is a good thing since it's getting rid of something). It does do some good job to get rid of sludge or whatever carbon deposits in the engine im guessing then.Valvoline says to change the oil with Restore & Protect four times for it to do its job.

I'm thinking about trying this for my next oil change. My engine still runs like a fine tuned compass but I guess at 140k miles it's probly got a little buildup inside that I can't see or sense. I'm always worried that these high mileage oils will hurt my engine that doesn't have any issues. And "high mileage" is a lot different for a different brand car than it is for a Honda. High mileage for some cars is 175k miles, for a Honda thats nothing. Valvoline says these additives are unique though and it all sounds good. I might try it.
"this oil uses a specific new additive technology. It's not done through the use of esters like their Premium Restore Cummins product. They also said that anything the oil comes in contact with it will clean. It cleans by dissolving carbon slowly is what they say. "
Well thats good/important to know.I did some digging online and a lot of reviews say your oil filter will get clogged up so you need to check it after 500-1000 miles (which i think is a good thing since it's getting rid of something). It does do some good job to get rid of sludge or whatever carbon deposits in the engine im guessing then.
This claim is BS. Started using Valvoline R&P in our 2014 4Runner at 365K miles. Changed at 370K and 375K and the oil was as clear as ever and so was the filter. Also no oil consumption.I did some digging online and a lot of reviews say your oil filter will get clogged up so you need to check it after 500-1000 miles (which i think is a good thing since it's getting rid of something).

After further research last night... it's hard to believe it would clog the oil filter in 500-1000 miles but I've yet to see solid evidence it doesn't do what it says it does. Valvoline says all over their website and press releases about this that you MUST use it for 4 oil changes for it to actually do its job. And not 4 drain and fills or short oil change intervals... four 3k-5k mile oil changes. It's designed to break down hard carbon deposits on things like the pistons which can't happen in 5k miles unless you're using a very strong solvent which isn't safe for every engine but those are available if you want that method.This claim is BS.

As stephenmras said it is BS. Or, rather snake oil. You have too much time on your hands. Go by what your owners manual says and let us know what is happening at the 500,000 mile mark. I got 310,000 miles on a 98 Accord with only changing the oil at the maintenance minder told me it was time. It never used oil, never had any issues with the engine.This claim is BS.

Clearly you're somebody who nothing could persuade you if you don't want it to.As stephenmras said it is BS. Or, rather snake oil. You have too much time on your hands.

There is a video linked above that shows it works well if you have sticking piston rings, it can be an option to clean it. For $30, it's nearly the same price as any other 0w-20/5w-20 you might use on an oil change for your accord. Might as well take the risk (if any) to extend your engine life. Isn't that the point of keeping these old cars if you own one at 150k+ miles at this point? To me, it's the same thing as adding a bottle of techron to your gas.As stephenmras said it is BS.
