Valvoline Restore & Protect 0w20

@AzusaPrius Any pictures?

 

All big brands will do a good job of protecting and keeping the engine clean. But anyone doing 10k mile oil changes and using 0W-20 is not helping the health of any engine. I personally do 3,000 mile oil changes and use Mobil 1 euro 0W-40. No oil issues and still high MPG.

 

If all big brands did such a good job of keeping an engine clean why was there a need to market an oil like Valvoline Restore and Protect? I think 5,000 mile oil change intervals are much more reasonable than 10,000 mile ones. Doing them at 3,000 is probably even better.

 

A sucker is born every day, especially those who neglected to change oil on time and hoping this oil will undo their procrastination

 

Any synthetic (group III or IV) engine oils can handle 5000 miles/6 months OCI for most case scenarios. Only some of us can do 10k miles OCI without oil consumptions beyond 200k miles. I also do 5-7k miles interval, depends on my driving conditions. In winter, short trips, I did 5k miles or less, and summer 7k miles. . I changed the oil in November and April .

 

Is all fine and dandy but in machine shop you learn that metal on metal creates friction and wear metalurgical wear and removal . I don't know if any lubricant that can replace worn away metal so far . They have made some things happen in this area but uhh not really ready for prime time etc . I really haven't been able to create our own personal oil related failure in 47 years of driving not so normally . Welp

 

Lake is one of the Oil Geek I am fan of. He does not push any marketing, just educative with science and number. All quantified.

No one can replaced wear metal parts with anything. The main concept on RP Valvoline is removing varnish and gunk. Additives like ZDDP and MoDTC are bonded to the metals, actually eat the metal a bit and create a hard glassy solid surface, this layer reduce the overal wear because it is replacable and as hard as steel. https://link.springer.com/article/10.1007/s11249-025-01968-3

 

Yeah right so when you go back and you put in proper rings and have proper sealing etc welp . Generally I had this control in my older Toyz. 22R 3S BEAMS JZ etc no lo tension nonsense poor sealing and all that . This crap was engineered in to try and extract nth degree of mpg . Well in my eyes you've got to know when to say when before the stupidity begins . And apparently.....
