Same here, my Dad was the first Dealer in WA. I have never bought AMZ/OIL for mileage increase but I am sure it does help "some". You can thank this company for pushing the others towards Synthetics.
In the late '70s I was a high school kid, working part time at a small engine shop. We had a valuable commercial customer who became enamored with the idea of using synthetic in his mowers. The head mechanic was not impressed, so the customer told him he could prove it was better. The mechanic started a commercial two cycle push mower, and checked the RPMs on idle. They drained the dino oil out of it, refilled with the synthetic and started again. The idle was roughly 500 RPMs faster. All of us were pretty amazed. I'm sure that this trick would be tough to repeat, given that two cycle mowers are gone, and I'm sure dino is a far better product that it was in 1978.
