2 Stoke oil- Can I use TC-W in an air cooled TC engine?

[ToadHill]

I remember working at a gas station while in High School. One customer had a 2 cycle Saab, we just threw in a quart of 30w with each 5 gallons of gas. Not that it answers your question but just an interesting fact.

I have used Lawn Boy 2-cycle oil for years in the trimmer and the blower. It has no API rating on it but is ashless and for all 2-cycle gas engines. It is reputed to actually be CITGO SUPERGARD Marine Plus Two-Cycle Engine Oil, TC-W3, may also be used in many air-cooled two-cycle engine applications requiring API Service Category TC.

Go figure.

I was doing some research.

Don't use it, I screwed up my and my neighbor's snowmobiles years ago with some "bargain" two cycle oil meant for water cooled engines.

I have to say, I don't know what to make of this subject. I have ridden 2 stroke dirt bikes, both air and water cooled since 1972 and with the exception of a YZ400E I bought new in 1978 that I ran on Golden Spectro exclusively, I have never paid any attention to the oil I have ran in my 2 stroke bikes, ATV's, chainsaws, weedeaters, blowers, etc. I know for sure, I have used a gallon of the Penzoil Premium outboard mentioned and a gallon of Wally worlds "all purpose 2strk oil" and a few quarts of penzoil and store brand "outboard" oil and a couple of cans of chainsaw oil in the bikes, atv's,weed eater and saws in the last year or so...with no problems with anything. We go through a lot of pre-mix, especially since we seem to be the "refueling station" for my 3 sons friends too. I have had very limited possible oil related problems w/ 2 stroke motors over many diffent engines and years. The only 2 strokes I have ever fried a piston in was the 400 that I ran on spectro exclusively and a 20 yr. old (!) Craftsman chainsaw. I had the crank bearings go south on a KTM 50cc motocrosser that one of the boys raced but I don't know anyone that's not rebuilding often in that class. My current water cooled woods bike has somewhere between 3-4000 miles on it w/ original piston and second set of rings and still runs like a top. I usually mix 5 gallons of whatever is cheapest at about 35-40:1 and burn it in everything air and water cooled we've got. I know oil technology has really advanced in recent years but honestly, I have had almost no problems regardless of type of oil burned in both air and water cooled 2 strokes. I have had far more top end problems w/ 4 strokes that I was actually somewhat "picky" about the oil I used.

I guess I should start paying some more attention to my oil but I'm not too convinced I will see any difference.

If I had a gallon of liquid cooled 2 stroke oil I would be dumping a little in my tractor and truck to help lube the fuel system. ULSD is kind of on the dry side compared to LSD of a couple years ago.

I would buy the air cooled oil for air cooled motors.

The TC-W3 oil I am using in the Stihl chainsaw is Valvoline.

Valvoline says on its website:
This product is recommended for all leading outboard engines, including the latest high horsepower units. Valvoline NMMA (BIA) Certified 2-Cycle Engine Oil will also provide excellent performance in two-cycle engines of motorcycles, chain saws, lawn mowers and snowmobiles.

I guess I have nothing to fear really.
