you guys know I test constantly and oil/tribology is my thing so here goes. I know the gasoline today is shit. Very dry and poor quality. Throw in ethanol and you got crap/corrosive gasoline. I use Fuel Power/Lucas UCL with great success in my cars and other peoples cars. At the first of the year some of us "lubrication physcho's" (mainly from the aircraft industry) discussed the shit quality of gasoline and the absolute advantages of running a fuel additive with lubrication capabilities and I think the testing is now complete and the results are very good. Biggest problem we had was the proper amount but we are now satisfied this works very well and you will have a smoother running engine/more power/better MPG....so here it is.....
What we are trying to accomplish ( The deliverables)
We need to lubricate the fuel pump/seals/injectors.
We need to clean the fuel system and scavenge water that ethanol attracts.
We need a film of protection in our fuel system to stop corrosion.
We need a cleaner for our spark plugs/valves/combustion chambers.
We need to clean the ring packs
We need to leave a film on the cylinder walls to eliminate cold start metal wear.
This was my groups short list of deliverables. Of course we knew if we accomplished this list the car should A) Run Smoother B) Run more efficiently C) Parts will last longer i.e. fuel pumps/injectors etc. D) We should see more RWHP and MPG
We did it. For pennies.
2 Stroke oil. Not just any two stroke oil But we needed the detergents etc. and found the perfect oil/add packs/viscosity in a marine 2 stroke oil you can get for under $10 bucks a gallon anywhere. We used Pennzoil Marine 2 stroke for our testing. Here is the "blurb" from Pennzoil.....

Pennzoil Marine® Full Synthetic
Ultimate Protection

Pennzoil Marine® Full Synthetic 2-Cycle Oil is designed for your hard-working, large displacement, high-horsepower 2-cycle engine. High temperature protection is necessary for higher horsepower engines. High temperatures in an engine can cause loss of lubrication, carbon deposits, piston-scuffing, and pre-ignition. The combination of synthetic ester base oils and a premium, ashless performance package in Pennzoil Marine® Full Synthetic 2-Cycle Oil provides protection for high horsepower applications that require approved NMMA TC-W3® oil.
Benefits:
Pennzoil Marine® Full Synthetic 2-Cycle Oil is recommended for use in those makes and models of water-cooled, 2-cycle engines with direct injection systems, oil injection systems or those requiring use of a pre-mix. It is recommended for and meets the warranty requirements of Johnson/Evinrude, Mercury Marine, Yamaha, Suzuki, Force/US Marine, Mariner and others requiring NMMA TC-W3® oils.

Pennzoil Marine® Full Synthetic 2-Cycle Oil:

• Performs in extreme conditions.
• Provides excellent lubricity to protect against piston- and cylinder-scuffing.
• Helps protect against ring sticking, exhaust port deposits, and spark plug fouling.
• Biodegradable and low aquatic toxicity.
• Recommended for direct injection engines.

Whether running full throttle to open water for that fishing tournament, cruising your favorite waterway, pulling a skier or racing you need an oil to protect your high-horsepower engine. Pennzoil Marine® Full Synthetic 2-Cycle Oil is that oil.

Use 1oz of the two stroke oil per 5 gallons of gas ( 1oz-5gallons/ 2ozs - 10 gallons etc. and that is the perfect ratio. Too much and it will make your engine run worse....too little and it wont do anything.....use the proper amount.....get a little bottle and keep it in your car.....We have seen a maximum of 5% better MPG down to a minimum of 2% better MPG. All of our test mules reported much smoother idles and cruising. No smoking or ill effects. No residue on plugs our pistons....actually the opposite....we saw "cleaning".....I am now comfortable recommending this for all. I also now run this mixture in my GTO/Mercedes/Silverado and G6 with all having smoother running motors and all gaining MPG. Give it a try and let me know your experience. Follow the mixture ratio to the letter. 1 oz per 5 gallons of gas.

wasnt saying it was shitty in that type of way but it is ranked higher than all other fuels(white gasoline)..... but truth be told all fuels were designed to make customers repeatedily(planned obsolescence) come back by wearing out things normal people are not aware of ie: a lil $3 pcv can cost you a valve cover gasket if you dont change it periodically ... next thing you know you got an oil leak next thing you know you got a broke motor mount, next thing you know your trans goes out......
