I was walking through a local sporting goods/automotive store called GI Joes, and I noticed that one has quite the plethora of different fluids at their fingertips. Gas treatment that says it will clean and give better gas mileage, super coolant that claims to lower engine temps by 40 degrees, various fluids that claim to clean this or that. My question for those of you more knowledgeable about cars than I (which is most of you), is that if any of these "miracle" fluids work and or make a difference in my cars performance? Are there any fluids that you would recommend I get? Please give me any useful advice.
