Fuel additive

[Renfield]

The maintenance schedule calls for fuel additive every 6000 miles. Exactly what is added to the fuel? Is it an off the shelf product? Why must it be done by a dealer?

Techron. The same additive you buy at Costco in a box of Six or your local auto parts store.

I had the service advisor show me. I now put my own in every 1000 miles and tell them to skip charging me 40 bucks for the same damn thing.

Thanks for the info. My GT1 AWD is still in the break in period.

I should have provided more context.. I had a 2012 Optima SX 2.0T and learned this from the advisor. I had that car for just a bit under 7 years (bought it new off the lot in 2011). Never had any problems with the engine when I put techron in and it ran great until the day I traded it in. I'll do the same with the GT2
