After first thing getting my '02 Sport 4x4 last year, 1st install maglite by drivers seat, 2nd install MagnaFlo muffler, 3rd K&N stock style air filter. 4th convert entire system over to AMSOIL both diff, engine, transfer case, automatic all to AMSOIL. 5th PIAA replacement bright head lights(Lots brighters}. Warranty work A/C system , rear Dif rebuilt discovered during Amsoil switcht out , new Radiator. LBJ's twice and just installed new Dunlop Rover A/T's 235/70-16.
I hadn't heard of L.O.S.T. yet . I couldn't tell of any improvements since I never got a Base Line to compare any thing to
Then after research I got a SCAN-Guage Model I then after reading and research and PM's Replaced my K&N Air Filer with the new AMSOIL dry stock drop filter. Well I've gone from 13.5 MPG to 16 to 17 MPG. I wont give all the credit to the Airfilter because with the Scan-Guage I I'll set it to milage and keep an eye on milage and keep my foot out of the fan more.
