DO ADDITIVES REALLY WORK ? OK SO I KNOW OLDER VEHICLES CAN USE SOME HELP NOW AND THEN....SORTA LIKE TAKING VITAMINS TO KEEP YA GOING. BUT A WELL MAINTAINED OR A NEWER VEHICLE SHOULD NOT NEED AND ADDITIVES ( RIGHT ) ? ! WELL ANYWHO I HAVE BEEN USING MARVEL MYSTERY OIL IN ALL MY ENGINES FOR 25 YEARS OR BETTER.....BOATS CARS LAWN EQUIPMENT TRACTORS MOWERS CHAIN SAWS GENERATORS ETC ETC. THERE ARE SO MANY PRODUCTS AVAILABLE IT'S MIND BLOWING. SEA FOAM SEEMS TO BE VERY POPULAR AS AN OCCASIONAL CLEANER. SO FAR MARVEL MYSTERY OIL SEEMS TO HAVE KEPT MY ENGINES RUNNING IN GOOD ORDER. What do you think?????

 

Gasoline engines still get carbon build up. Sea Foam, B12, and Lucas are the top 3. Also cleaning your throttle body, and changing your fuel filter regular will help too.
