Re: Does the type of 2 cycle motor oil really matter
WELCOME DAVIDDM!!!
Just in case you did not know this, the TCW-3 rating that they are talking about here stands for Two Cycle Watercooled (engine) 3rd specification.
(there was a tcw 1, 2, and now 3.....their will probably be a TCW4 someday).
NEVER run 2 cycle oil that is made for lawnmowers, weed-wackers, chainsaws, ect... These are Aircooled engines and have a complete different oil needs and spec's.
ALL TCW3 oils are made to be able to mix together without gelling or causing other problems...but the common thought is to try and run the same oil in your oiltank if you can, and when changing brands...run out or drain as much as you can from the oil tank prior to refilling.
I also run the PENZOIL Premium Synthetic blend in my 1978 Johnson 115hp.>>> I tried a bunch of the oils from West Marine & Boaters World...they made my engine smoke a lot...NOT the penzoil!
The engine has been VERY happy running on the Penzoil>>>Less Smoking & it idles smoother...AND its a lot less money!!!
