As a teenager with Grandpa's old 1955 10HP Mercury I used to rent an old tinny up the creek and terrorize the ducks on the Erie Canal with my buddies.

But I DID religiously use "good" oil and kept to the 24:1 ratio. I bought Quaker State 2-stroke OB OIL because that 's what they sold at KMart.

One year I having smoking and running problems, so I took the motor to my local Mercury dealer. Rather than going to the retail store first I simply went to the back door at the shop.

The manager there said it would be a diagnostic fee and it would take weeks. But he offered to let me dunk it in his test tank and listen for free. I started it up and he immediately said shut it down. "You have been using Quake State OB motor oil". I said, OMG that's true. He gave me a bottle of Mercury oil and said good luck.

All these years I still have an old empty plastic bottle of QS, just for nostalgia.

That's my oil thread for the day......LOL.

A closing unbelievable remark about gas to oil ratios.
Way back a test group decided to see how little oil could run a 2 stroke O B. They settled on 300 something to 1. Even I would not go near that on a dare. Anybody know for sure. What ETEC ran on in California to get EPA and California approval ?

But E-tec is a different concept.---Oil is NOT mixed with the gas.----Gas is not in the crankcase to wash oil off the bearings.----An E-tec operates like a 4 stroke for part of a revolution of the crankshaft.
