Fill Her Up......High Test
Here we go.....I realize our C5's have a duel gas tank. Does anyone know how they fill up? Does one fill before the other? Do they fill at the same time? When do I add my additive? Every once in a while I like to add a bottle of fuel injector cleaner to my gas. One time I poured in the additive before I put the gas in. My gas needle took a long time to go from empty to full. So now I add the additive after I fill up. Question is, where is it going? Does more of it go into one side than the other? I would like to distribute the additive equally between the two tanks. So what do you think ? :grouphug:

Re: Fill Her Up......High Test (vette#one)
I've used a lot of gas additive (like 104) in Corvettes, and I just don't think it's worth it. It trashes the plugs and oxygen sensors (I've SEEN it). The best solution is to find yourself a local supplier of racing fuel, like Union 76 100 unleaded, add about 3 gallons per tank, and the car really wakes up without any fouling problems. It's expensive (about $7 per gallon), but maybe not much more than additive, but it's definitely better. I don't know exactly how it fills with dual tanks, but it's been no problem for me. Pour it in and hang on.

Re: Fill Her Up......High Test (C5+ZR1)
The driver side fills first, then the passenger. However, once the car is running, the pump equalizes and mixes the 2 tanks. I would just dump it in before the fuel, imho.
I have run additives with no problems.
