Careful; using 20 Gal may melt down the engine.:rolling:Go get a bottle of Techron at Autozone.; and if it's available stick with Chevron gas. It's got techron in it.:thumbsup:
I used to have that trouble all the time untill I put that in.
The first time mine did it I bought a bottle (20 gal size)then filled it with gas and the problem was gone by the time I got home!
Also go ahead and google "Top Tier Gasolines" It explains it.:cheers:
