Use any reputable gas from a high turnover source and you'll be fine. I've used Techron System Cleaner (not the watered down stuff they sell at costco) in the past. That does work. I had some pinging in my old car with 200Kmiles on it and it all went away after 1 treatment. [Edited by: mybigtruck at 5/15/2013 3:28:28 PM EST]

Clunk49 Rookie Author Nashville Posts:23 Points:2,635 Joined:Nov 2012	Message Posted: Apr 1, 2013 9:35:14 PM Ignore Clunk49 Report Abuse I add Lucas Upper Cylinder Lubricant to lube the 18 year old intank fuel pump on my gasser. Ya gotta remember, fuel cools and lubricates the electric fuel pump. Letting one run out of gas hurts you more than just getting out and walking to the gas station.

Mandrake Veteran Author Alabama Posts:497 Points:2,207,855 Joined:Apr 2004	Message Posted: Apr 1, 2013 7:32:09 AM Ignore Mandrake Report Abuse I add SeaFoam to one tank of fuel each time oil is changed (~15K miles) for a bit a more hardcore injector cleaning than Techron offers. No reason for timing with the oil change except as an interval reminder. Apart from that, just use Chevron/Techron gas. I've not driven without adding something to clean the injectors every so often, so I don't have a frame-of-reference with regard to possible performance lost or gained. In short, I do use an additive as occasional preventive maintenance but not as a performance 'enhancer'. [Edited by: Mandrake at 4/1/2013 7:33:30 AM EST]

It also cleans injectors. It gives me peace of mind and my car runs great. _____ After looking over the MSDS for Seafoam, I do not see anything that would stabilize the gas or counter ethanol. It's a cleaner only. Products like PRI-G will stabilize and reclaim fuel. It also is very good at keeping engines clean so they don't need a product like SeaFoam in the first place. Of course, using a Top Tier fuel is all anyone would need to do in the first place. _______ We should also be clear about the claims of additives that they will improve mileage. This is not what they do. If the engine has lost mileage due to combustion chamber deposits, as one example, these product may potentially restore that mileage but they cannot improve mileage over what the engine produces when it's in good condition.
