Valvoline Restore and Protect 2AZ-FE Observations & Questions

Stick with the VRP and give it the full 4x OCIs. My own yearlong experiment with it was STILL showing cleaning after the 3rd OCI. But this was also in a very varnished old Honda J35a7 with over 200k on it.

How effective was it with the varnish? I imagine that takes some time.

You won't really know if the VRP is continuing to clean until you cut the filter or otherwise inspect it (if it's a toyota cartridge filter). VRP cleans and parks the residue in the filter.


VRP can undo deposits, but the long term effects of all the prior miles with deposits cannot be undone. Wear is wear and damage is damage-- they are the eternal entropy of engine life.

Exactly...once engines start to wear, rate of wear only accelerates.

VRP is great, and this story is compelling.

My 2005 Tacoma 2TR-FE 2.7L 4 cylinder consumed oil, but I got 750k miles out of it.

I have adopted a maintenance plan involving consistency and using highest quality synthetic from very early in vehicle life.

He's posted photos here. The varnish removal is impressive.

If you were continuing to see cleaning, why did you switch away? Just curious.

He said replace them. That's how he makes money.

Before VRP, there really wasn't too much of a choice. BG EPR and Berryman's B12 I suppose, with variable success.

To be fair to TCCN new pistons and rings are absolutely the best solution for these engines. If either of mine qualified for the service campaign I would absolutely have it done. Since they don't I consider myself lucky that the piston soak is so effective because there's no way I'm spending 4K for new pistons on a 5K car with cosmetic issues.

Because after the 4th drain the cleaning had drastically slowed and frankly I have oil ADHD. I have a lot of oil on hand and honestly I need to start using up some of the older stuff. My SN-rated 0w-40 FS is what's in there now.

Almost complete removal in one year. If It had been driven more than just 8k miles or so, it probably would have been completely removed.

Nice. Good to have a real world example.

I need to grab an updated pic and post to the series of oil fill hole pics.

Yeah please update us. A compilation from start to finish would be great.
