    Great collab! One of the things that impressed me about Repair Geek is that he does this stuff in his garage. He's not programing a duty cycle into a dyno, he has to drive the cars.

    Great collaboration guys! Lake, thank you for the additional info on Pennzoil Ultra Platinum. Have to admit, I’m one of those guys that gets overly focused on the chemistry. Your update made me feel better about all the PUP that I stocked up on back in March. Thank you both!

    You will never get from Phoenix to Tucson using I-15. I-10 is the road you want.

    For an injector test. Find an old V8 to get 8 dirty injectors out of. Flow test them on just pump gas. Run a different injector cleaner in each one, and test again.

    I have 2013 chevy Silverado 1500 5.3 280,000 miles. It was burning 2 quarts of oil between 5,000-mile oil changes. I did 4 5,000-mile changes and it dropped to 1 quart at 4,200 miles. So, I did a fifth run 5,000 mile and it used less than a quart this time. Also, I put shell 87 gas in it and add a bottle of STP COMPLET to the fuel each oil change.
