Why do you seem to be so scared to use VRP? I use it with my turbo tuner Hyundai in the cooler winter months here in Minnesota. I run 5W-40 or a 5w-30 HTHS of 3.5 during the hot summer when I "really am beating the crap out of my car on back roads". I know you have Hyundai/Kia's so you are very hard on oil just because of the Hyundai/Kia brand, but I figure you are not doing full WFO pulls at every on ramp. You would be a perfect use case for Valvoline Restore & Protect 5w-30. Heck I even idle my Hyundai 3-4 minutes every startup in the winter and about 2-3 minutes every start up in the summer to expand my pistons before hitting them with 22 psi of boost. That is adding more stress on the oil on top of it.
I just don't see a valid "use case" from your car selection to "fear" VRP while putting in Rislone "oil additive". With modern day "premium oils" and your playing an oil chemist fearing "wear"????
This is from a previous post I posted a day ago:
I have not pulled any UOA on my 3) 3,000 miles fall-spring and a 4th VRP is up coming in 2-3 weeks, late spring and summer my car will get my stash of 5w-40 Motul 8100-Clean Gen2. This VRP 5w-30 has been the cleanest running oil ever in my car. Nothing has run cleaner as far as color, most all my top tier brands ( Amsoil, Redline Performance Euro, Mobil 1 Extended, Mobile ESP/2 years, Penz Ultra, and Motul), run to black at my 3,000 mile dump, this stuff is still in the brown/black color. I think I will pull a UOA and send it to the large local CAT dealers lab where I have a couple other pulls. No need for Polaris Lab, since I no longer have massive fuel dilution problems like I use to have.
I saw a couple people say their UOA came out with the least wear metals of other oils they have tested. VRP "SAYS" it is a premium oil with 79% better wear protection then what "Jim's oil" at the five and dime?. I know color doesn't mean bad or a less quality oil , but when ALL these top tier oils get very black at 3,000 miles and VRP is the first oil not to get black and actually show a light brown in my car that "might" be telling me something, it sure caught my eye.
Just saying............. Your oil robustness fear VRP just because of viscosity, on a none tracked and what I will assume, non beat on car like say mine is. Now I am for sure going to pull a UOA after 3 changes of VRP I will have zero "other brand" oil residual in the test.
