I use chevron gas and use injector cleaner every oil change.

Am I over doing it?

 

i like to use some lucas oil fuel injector cleaner every 3 oil changes or about 3 times a year. i put it like a 1000 miles before im about to get an oil change though cause the fuel injector cleaner mixes with the oil and degrades the lubricating properties.

 

I run a can of Seafoam into my fuel tank once a year or so.

 

"fuel injector cleaner mixes with the oil "



i'd bloody well hope not - unless your accent is a 2 stroke

 

^ in the same way gas mixes with the oil . . .past the rings.

 

fair call, but i would say it is in such minimal amounts that it doesn't amount to anything. i mean, 400ml of cleaner in a 40 litre tank is a low enough concentration. if you then consider the amount of gas that would make it past the rings... unless your accent is a few million years old and throwing blue smoke out of the exhaust, i doubt this would be a problem.
