i own an o3 evo and got about 28000 miles on it and am planning on doing an oil change tomarrow my last one was at 25000 miles. I was looking at some autozone stores and have seen many products that claim to reduce engine wear and help gain power when mixed with your engine oil. I love my car and am very sceptical on what i put in it, i only use shell v power and have only ben using mobile 1 synthetic. Has anyone tried products like these if so what are the results and what kind have you been using. I dont mind cost, if theres something out there that will give my car even the slightest of reults ill buy it, also what can octane boost do to a stock 03 evo? ive heard of speed gain and lower 0-60 start times but will they work on a stock evo? or is the octane to high?
