Okay, I've done all the searches for MMO, and why I'm puting it in is because my engine may be carbon locked. In all my searching I have not been able to find where to put the MMO in a fuel injection engine. I don't have a carburator, so I can't put it in there. Where do I put it??

Into the bottom two spark plug holes.

Are you sure it is carbon locked? Have you tried to turn it by hand?

how much MMO should I put in each hole??

If it is carbon locked you can take it to a mazda dealer ship and they can put a reverse starter on the engine and unlock it call you local mazda dealership and talk to the rotary tech in the shop and see what he says.

only one problem with the reverse starter--it is only a temporary solution to a not-so temporary problem.....it is like putting the car in 5th gear and pushing backwards--it might free up the seals but it doesn't get the carbon out of your engine! Not to mention that when you have something stuck against the rotor housing like that and you turn it, you risk damaging the surface and your seals......better off to go with the MMO or ATF....after all, if you're carbon locked, then your engine can only benefit from getting rid of more carbon at the same time, right??

there are also two ways to get the MMO into your engine. I would go with the lower spark plug holes....use a turkey baster and put about 1 ounce into each hole. There are also valve fittings on the top of the block, and from what I have been told, they were put there to put oil into the motor. You attach a squirt oiler hose to the fitting and shoot some in. I say just go with the spark plug holes, since you're gonna want to pop out the plugs and clean them up after anyway
