    Your engine doesn't need anything except plain ol oil. I don't know why people buy that nonsense stuff.

    Acting up how? Go ahead and take that crap out of your engine and fill it with regular oil. I've run plenty of cars on regular dino oil for the life of the motor and as long as you change it regularly there is no problem at all

    HI

    You don't need to mix it with oil... You pour it straight into a warm motor.. Or cold (tho it should be warm so it flows better..) once the motor is run it well mix the STP into the oil.. A little more information would be nice like HOW is it acting up?.. might not have anything to do with the oil or the STP. All STP does is thicken up the oil a little to help it stick to lose parts and somewhat quite up a noise motor.. What cause you to want to put STP in it?

    how much did you put in ? one can I hope.

    good luck

    Last weekend I got a deal on STP OIL TREATMENT at Advance Auto parts .I drive a 2000 Ford E-150 van /4.2/V-6 engine !I was goping to drive my wife 120 miles to get her Cancer Treatment .We got 40 miles and the engine started to tick and valve noise? The oil pressure would drop down to 0 and then back to normal every 30 seconds! I shut the engine of and had to baby it all the way 40 miles back home! I changed the oil and filter and now it is almost back to normal! NEVER USE THIS STP CRAP EVER!

    I use to put additives on engines too without mixing it with the oil first, just adding it though when the engine is already warmed -up and run engine again after pouring the additive. If you were able to warm your engine after you poured your STP oil treatment, there's no reason for you to worry. These addititives had been tested to help prolong your car's life not ruin it.

    it should mix with the oil once you start your car. i used it before and never had any trouble.
