Valvoline Restore & Protect

[panthermike]

Ran this in a 2008 Sequoia with the 5.7 3UR engine. Engine had a plugged PCV for who knows how long. Initial R&P fill ran 5k miles and a ton of buildup was in the oil filter. Impressive for an initial fill but I’d use caution if you know your engine has a lot of buildup and shorten the OCI to avoid an oil filter restriction. Oil consumption went from 2+ qts on a 5k OCI to around 1qt. Also ran 5w30 R&P vs the 5w20 or 0w20 synthetic previously for full transparency.

Wow, that's wild! Are you going to keep running the VRP for a a few OCI's at least?

Yeah, that’s the plan. My family member that drives it now doesn’t put a ton of miles on a year, so it will probably be a while before I get an update. I’ll likely change the filter mid-interval this time to be safe.

185k miles, has been in my family since 130k and ran Mobil 1 or valvoline synthetics since I’ve owned it at 5k OCI. Previous long term owner primarily ran conventional every 5k. Good oil change history, plugged PCV caused excessive crankcase buildup prior to me owning.

If that's accurate (5K OCI's with conventional) then it underscores how that strategy, prescribed by many on here, can utterly fail at keeping an engine clean.

Devil's advocate: did the build-up result in quantifiable performance issues?

A lot of the blanket or one size fits all statements often written here can get some people in trouble. Statements from back in the day like a good conventional oil can go 5K miles, or a good synthetic oil can go 10K miles, IMO for many of us that's looking for trouble.

Good question. I'd assume if it was put on a dyno, it would be down on power, but maybe @YotaGearhead can let us know if there were any observed issues with the engine.
