I know someone that got well over a half million miles on his 4 cylinder 8 spark plug B2300 Mazda pick up. How many others out there has gotten high mileage from thier Mazda truck? If you did is there anything you had to do to get that high mileage? He said all he did was add oil when it got low. Just sounds strange to me and the truck went that many miles. His water pump went out and he drove the truck knowing it was bad. He could have gone more miles on this truck. It was a 96. I bought a 2000 ford ranger with the same motor thinking that I could do the same but have had nothing but problems with it. Guess Mazda in 96 put together a winner in the B2300.
