I've maintained the 2007 toyota camry 2.4 2AZ-FE in my sig since new. Up until about 315,000 miles it got Mobil 1 Advanced Fuel Economy 0w20 every 5000 miles. Doing this, it eventually got to the point of burning 1 to 1.5 quarts every 5000 miles.
It took four 5000 mile oci's of Valvoline Restore and Protect to make a difference with this engine but it certainly made a difference. The car now has 353,000 miles and it burns a very miniscule, negligent amount of oil every 5000 miles. This was not a dirty engine, it wasn't perfect but if you care to look in my history, I had the valve cover off a couple years ago and snapped some pictures. I know it doesn't mean a terrible lot, but the oil does stay cleaner longer which does indicate better cylinder sealing with not as much blow-by and carbon making it to the crank case.
You're going to make some Mobil 1 fanboys(girls) mad with that statement.
They claim users of Mobil 1 don't burn oil, their low-tension oil control/piston rings are absolutely clean with no carbon build-up & don't need to switch to Valvoline Restore and Protect.
Do you plan to continue with Valvoline Restore and Protect?
There's still some debate if the 4 shorter OCIs at severe service schedule are sufficient as Valvoline originally stated normal service schedule, which usually means double the mileage; hence the number of OCIs should be increased.
