I tune cars and I hear spark knock ALL the time from cars pulling away from stop signs during the summer - including cars that specify 87 octane. A lot of engines come with poor calibrations (especially early GDI engines) and are running higher cylinder pressures these days. I’ve insisted some...

You might see a difference from the 5w-20 if you extend the interval, but 5k is too easy for both oils. I like that you’re spiking your 93 with E.

Don’t call him Shirley. Also, yes. If your goal is to dilute your quality stocks abs additive package with a potential chemically incompatible additive, then go ahead and use it.

Your gut instinct is right. The service advisor is wrong lol.

Another easy long term oil interval with an “old school” NA engine - IMO, the engine that should be on most eco cars today.

For driving around on the street ZRod 10w-30/10w-40.

Stick with Valvoline Restore and Protect for 4 intervals then introduce more intensity into you interventions.

I can’t wait to try it out. 0w-40 UOA should be coming if anyone else beats me to it.

I’d ignore the sample size. In this case, the largest predictor of wear is break-in and he has regularly cited this confounding factor in lab results. I was flabbergasted when he mentioned break in effect, then made the conclusion. I was literally jaw dropped.

Why do you keep changing oil?

And actual cold. -30C for a couple of months.

This is the way.

Yeah let me know what they charge. I generally tune everything else, somehow I’ve avoided Holley. I don’t mind helping out a fellow BITOGer though.

But that would be EVOLUTIONARY!

He’s running a stand alone ECU. The stock maps ain’t going to work.
