Indeed. When you mis a down shift, there is precious little the car can do to save you.

One follow up question. How often or when should I be adding an additive, or will running Chevron with Techron consistently keep the carbon deposits low?

Hi,

I add a Can of Jectron at the start of the season, in addition to working on engine deposits, it cleans the Injectors and Valves - the $10 Tune-Up '). Using good Gas and not storing it for extended period will usually be all you need to a year-round car...

Jim...

I thought I read somewhere on here that the injector cleaners may leave some stuff in the oil. Would it be better to run the cleaner 3000 miles prior to the next oil change? That way that stuff won't stay in the oil all year round?

Just wondering, since I have some techron I'd like to run in mine sometime. Just deciding when to use...

Thanks
Georg

Hi,

It is better to do this prior to an Oil Change, but in the case of the Jectron, not absolutely necessary. Any Jectron which get into the Oil will Flash off. So far as Techron, I cannot say. Check their MSDS sheet and look at the volatility statistics, that should tell you...

Happy Motoring!... Jim'99
