Fuel and Oil Mixture

[havingfun]

What fuel and oil mixture should I use for an older Mercury engine that hasn't run for at least a few years? <br /><br />As far as I know it is in decent condition.<br /><br />Thanks for your reply.<br /><br />Tim

Re: Fuel and Oil Mixture

Normally a ratio of 50 parts fuel to 1 part oil (TCW-3) would be good for this type of engine. With older engines or when breaking in an engine I'd drop that to 25 to 1.<br /><br />If you get too much smoke - or don't care for it much then look at ashless oils instead of the standard TCW-3.<br /><br />Your manual may say to use TCW or TCW-2. TCW-3 replaces these.<br /><br />=-bayman

Thanks for the info.<br /><br />I've never heard of ashless but I'll ask around.

It's probably more commonly known as smokeless come to think of it. One of my local dealers usually sells Sierra smokeless for between $5 and $6 per quart. Not to push any particular product - that's just what they usually have in stock. I'm not sure if any particular brand is better than any other.

Re: Fuel and Oil Mixture


if it hasn't started in a few years it might be a good idea to take out the plugs and squirt a little oil into each of the cylinders and let it sit over night and then the next day squirt a little more oil in each one and pull the engine by hand a few times if it is electric start, if its pull start just give it a few slow pulls to circulate the oil a few times, this is the minimum I would recomend if it turns over and starts well it would probobly be a good idea to check/replace the impeller, lower oil, spark plugs, carb clean basically give it a decent tuneup....good luck
