Valve was changed shortly after purchasing. Probably within 10-15k miles after I noticed a small amount of oil residue in the intake pre-throttle body where the PCV should draw air from, not vent to. Confirmed with vacuum gauge placed in the PCV fresh air tube that engine was building pressure...

The buildup had no ill effects on power or performance other than some oil consumption which I’d suspect is caused from carbon deposits in the oil control rings. That was the primary reason for trying out Valvoline Restore and Protect.

Based on my 15 years in the industry servicing Toyotas, 5k intervals on conventional doesn’t typically pose a problem (for Toyota at least) aside from those exceptions for vehicles that fall under “severe” conditions. In this instance, the lack of crankcase ventilation flow caused a lot of...

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.

Debris caught in the filter on previous oil changes was barely noticeable, I’d notice a couple small fragments here and there but I was definitely surprised this go around. A lot was knocked a lot loose over 5k miles. I’m also trying this out on a couple oil burning 2nd gen Prius’. Curious to...

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.

Ran this in a 2008 Sequoia with the 5.7 3UR engine. Engine had a plugged PCV for who knows how long. Initial Valvoline Restore and Protect 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...
