We don't know that. Doesn't take much cobra venom to kill an elephant. :giggle:

How do we know whether the residual R&P still in the engine didn't do this? Jumping around to different oils at each OCI tells us little.

I just did a 'spill 'n fill" to the tune of approx. 3.5 qts. in my 2009 Toyota Corolla with Valvoline Restore and Protect today. I will do it again in a few thousand miles per mechanic suggestion.

Major thread drift here....:rolleyes:

Only if it's a Formula One car and you are "cold" starting it in Death Valley at 2 PM. 😏

Indeed it was. Here's an excellent history lesson:

Yes, and according to reports: "Group III crude is processed by three refineries in Qatar, UAE, and Bahrain. Qatar's refinery is currently offline due to damage it sustained..."

Lake Speed Jr. said Valvoline Restore and Protect works better at higher ambient temps and long trips at higher speed. He also stated in an Amsoil test that there is no 'best' motor oil, but rather best oils for specific scenarios. It us up to you the consumer to determine which one that is.

Why not play it safe and do the Valvoline Restore and Protect 4 OC full cycle and afterwards make your own subjective decision, noting any changes in idle, power, etc.? You have nothing to lose.

Why is the fact that Valvoline engineers recommend 4 OCI's "clumsy"? After all, I'll assume you are going to keep your vehicle for at least that time period. As well, if after 4 OCI's you feel as if there is no noticeable change then what have you lost?

The Dunning-Kruger effect.

So, tell us what YOU see here?

All I know is that yesterday my mechanic changed the PCV valve & oil sensor in my 2009 Corolla with 227,000+ mi. and he remarked with shock how clean the oil cap area looked inside and that the engine purred like a well oiled sewing machine. :) The car runs like new and oil consumption is down...

Back on topic... I am approx. 1,000 mi. into my #4 OC with Valvoline Restore and Protect 0W-20 in my 2009 Toyota Corolla LE which has a little over 227,000 mi. on it. Last Mon. I had the timing chain tensioner replaced as oil was seeping around the plate. I read it's quite common on high...

I don't think some here quite fathom the technological leap that Valvoline Restore and Protect is and more importantly that other cos. are rendered essentially 'impotent' by patents viciously defended by hordes of $500+ per hr. legal teams. The "self cleaning" factor has literally changed the...
