Ok here is my question I have an 87 k5 blazer 4 speed manual. 85 and 89 Chevy trucks all with the 6.2l diesel engine. Im trying to get the most life out of my engines and injection pumps. Also are there any ways to get more fuel economy out of them.
Also my other question was oil I have been running mobil delvac and 20% Lucas in my engines does anyone else use it or has anyone had any adverse effects from using it and if you are using it how many miles have you used it for
