The manual says not to use any "Maganese based" fuel additives. What the hell does that mean. Is it safe to run a bottle of Techron through the tank to ensure the injectors/rails are clean and and stuff..?

i just ran a bottle of the lucas injector cleaner with the last tank... car runs just fine, and it took the "pinging" away. When the injector clearner was put in i also used 89 octane chevron gas... and ill tell you what.. the car ran like it was brand new again!
So i think you should be ok.

lucas has a lot of products, and I would never use an oil additive, however they have one of the best fuel cleaners/lubricants i've used. you can actually tell a difference.

GTnAZ

that exactly what i am saying... you will notice the difference!!

And yes i wouldnt recommend using the oil additive!

What's wrong with using an oil additive? I have not used any but I didn't think it could be harmful.

I've also heard horror stories about oil additives specifically Lucas oil additives..

most oil additives cause the oil to foam and when cold become too thick. rather than mask a problem, fix it!

the most I would say putting in your engine would be a high milage oil, like my valvoline max life.

i have an oil burn in problem, but have soon plans of fixin it
