If your adding it to your fuel I'd be careful. I'm pretty sure it's not oxygen sensor safe.

Truthfully, unless it specifically says it's ok for 2 stroke engines I would not use it. Why take chances on something that costs thousands of dollars? Makes no sense to me.

Your right I'm going to check the directions on the bottle if it says nothing about 2 strokes then I'm not going to use it, but I will continue it in my car, does anyone use it in there car? I'm telling you it gets better mileage

Be REAL careful adding anything to a 2 stroke... Thinning the fuel leans the air/fuel mixture

Back in the day my mom had a Ford Explorer that the valves pinged like crazy in. Put some Marvel Mystery Oil in it and it never made a sound. Stuff does do wonders however I don't believe it's safe for 2-strokes.

My dad was a mechanic for 50 yrs. incl. time in the Navy wwll. he always said the best thing you could do for your car/truck was change the oil and grease it every 3k miles. He didn't like any additives. Said some would loosen crud so it ended up causing problems. On older engines some of that crud takes up slack and prevents bypass etc.
So I never use them, as my vehicles have mostly been older high mileage ones. recently had a friend start talking about adding power steering fluid to oil. (old trick to quiet lifters) I started to tell him, when he said it cleaned up the engine inside really well. he said "let me finish. For an engine rebuild, prep by three ps fluid treatments at 3 oil changes will prep the engine for a rebuild. inside parts will be shiny as new saving time on cleaning for rebuild." my car always seems to run better after I wash and polish it ; ) Last edited by 13Echo70271; 07-08-2016 at 01:35 PM.
