Is Phase Guard 4 recommended for use in my Corvette engine?
Phase Guard would work well in your Corvette. I have used this product, exclusively, for 3 years and I have never had an issue.
1oz. to each 10 gallons
Recommended by my boat dealer
I had fuel/carb problems resulting from ethanol in gasoline. My nissan 9.8 hp outboard would become difficult to start and idle rough. The use of phaseguard 4 helped my engine start quicker and run smoothier. I add an oz or two to my tank before filling up. My engine ran well all last season. I will be adding this product to my outboard's gas tank and saving the stabil for the lawnmover and small power equipment. Phaseguard 4 was recommended my my boat motor mechanic/dealer.
