Johnsen's HT-200 Hi-Tach Heavy Duty Oil Stabilizer - 32 fl. oz | Engine Protection Additive for High Mileage Vehicles | Reduces Friction & Extends Oil Life | Ideal for Trucks, SUVs & Performance Cars

i've been using hi-tach in all my motors for years. I truly believe in the product. use to you could find hi-tach everywhere then in the last 5 years the only store that sold it was my local napa store. and now they say they can't get it anymore. so i lucked up and found it on amazon. and its cheaper than napa was....good deal
