TOPIC: 1997 chev 1500 pickup 350 vortex

a bud of mine has good things to say about " EnviroMax Plus " gas additive so added 3/4 oz to 32 gallon tank fillup 2-11-15 with 8 aspirin in 3 oz EverClear 190 proof 1/2 oz H2O2. See how truck likes this after about 3 tanks

Talk to my bud about what is different between emission and non-emission gas. We looked at papers he has from doing gas station work for many years, his father did for long time still working and we found something is being put in non-emission gas and now looking for a filter to remove what ever it is. gas 2.15 now

Update 6-18-16
I have lost my 1997 chev truck in a wreck insurance company totaled my truck because of being 19 years old. Would not even talk about letting me have truck repaired for part $1000.00 on line and labor about $1000.00 maybe. Still have truck with salvage title. Drove it to Atlanta and back runs great.
I did find me a 2015 GMC v8 regular cab long bed and need to groove it soon but I need some help as to how to get this new stuff groove. If anyone can point me to a GMC truck been grooved on here it sure would help. Thank You
