Never, if you're asking me. Most GOOD mechanics won't either. The ones I knew wouldn't. That stuff is sales incentive material, you bump up sales to DIYers with it.
To Cobb, how do you have all those problems to even begin with? The FI system has been 100% flawless on every MPFI car I've ever had.
I still feel 95% of that stuff is owner-in-head invented. 45+ years now driving cars with none of those issues................how do ya'll have them? And all the people that told me typical stories......if I could get close to the cars I could tell no way were they running as well as they said. I'm an expert on self bullsh-tting, having had to wade through tons of it for a long time. Not saying that here but saying as an overall picture................take it or leave it.
You DO realize that regardless of what the company says that anytime you flood the cat enough with ANY petro distillate to smoke heavy out the pipe you ARE damaging the cat in some fashion. They won't tell you that of course, the problem does not show right then unless cat on its' last legs. Like the guy last week saying Bon Ami didn't scratch glass because they said it wouldn't. The MSDS proved otherwise. You're in a Republican business prosperity ONLY world, wake up.
In my world I don't waste a penny on that stuff. Fuel system cleaner? The gas itself is required by federal mandate to have cleaners already in it, if you got issues change where you buy gas. Change your fuel filters, they are now water collectors like diesel ones if you use ethanol in your local area. Once filter filled with a lot of water some of it pushes through to engine and then problems (pinging).
And why flush MTX oil to go to syn? Unless ATX fluid vs. oil they mix readily with no issues.
If you knew what was in seafoam you'd realize you can use other things at 1/3 the cost or less. Change gas to get more fuel cleaners for the lean code. Water (free) instead of seafoam in the engine and very carefully in small amounts, ping gone.
