It's viagra for your engine. :dance:

Really, it just helps keep the engine from collecting deposits in the fuel system. Keeps your injectors from clogging and such. Deposits in the system can cause the engine to run poorly or go beyond the thresholds of the 02 sensors. You can buy bottles of it at most auto parts stores if you don't have a Chevron nearby.

How often should someone use additives like Techron? I know it improves gas mileage and with today's gas prices it's a smart thing to do but what is too much? Every 10,000 miles? 5000? 3,000?

I wouldn't count on saving $$ due to higher gas mileage if you have to add bottles to other branded gas. The cost of the stuff is >= what you will save due the little bit of higher mileage you may get.

If you get the Chevron gas, it's in every tank. If you have to add it from the bottle, I'd put it in every tank, but I'd find out how much is in put the Chevron gas and match that amount.

All in all, it's easier and cheaper just to put the Chevron gas in it rather than buy the bottles (or Texaco now that it has Techron added too )

Unfortunately I don't have Chevron stations in my area. I was thrilled to learn a couple of weeks ago that Texaco now included Techron in their gas. It's now the only gas I will burn in the 986.

I don't know if O2 sensors are covered under warranty. I would take it to the dealer and see what happens. Please let us know how it all turns out.

Best of luck,

The saga continues....I filled up on Wednesday and have driven it about 40 miles since and this morning when I started up, the light is off again. Hmmm....car seems to be a little fickle!

I have invested in a code reader from ebay for $30, so I will be ready for when it comes back on. I'm hoping that I just got some bad gas the last time. That is when all this started, with that tank of gas. We shall see..........

Thanks for all your input.

Not to be a pain but why not just take it in and get it repaired by a competent mechanic?
