He lost me right off the bat claiming OCI were always 3 months 3000miles. Thats 100% verifiable BULLSHIT. I got owners manuals from my '67 Galaxie saying 6month or 6000 miles ....and thats with the primitive oils from the '60s. I also have some from the '70s and '80s with 6/6000.
The 3/3000 crap started SOLELY from the quickie oil change chains in '79 or '80. Pure invention of marketing...look it up.
Then, he proves NOTHING. Using the phrases many times...."In my opinion...", "thats what I heard...", "this is what I think....", ZERO proof or scientific evidence to back up a single word he said. What a load of ****. Guys a mechanic NOT a tribologist or engineer. He also never mentions used oil analysis. Everything he says/claims is just "guesswork" at best, or he's a slick salesman trying to seem like 3/3000 changes are justified. Only way to PROVE oil is bad and actually needs changing at 3/3000 is by ACTUAL TESTING.
Oh and the fact he has a man bun, let alone a 60+ year old with a man bun sure doesn't help. <ok, that was meant more to be funny then any crack at his credibility.
