For obvious reasons, fuel economy is more important than ever. I am hypermiling as much as i can but have only owned gas cars for the past few years. Now i'm trying to squeeze every km i can out of each tank in this thing: https://bobistheoilguy.com/forums/threads/my-new-horrible-beater.361149/
What i've done so far is the basic stuff: new air filter, new 15W40, high tire pressure. How many of you have experienced increased fuel mileage out of switching to synthetic/lower viscosity fluids specificaly in your diesel cars or trucks? I'm asking about older IDI diesels. I'd switch to 10W30 HDEO, synthetic ATF and synthetic lower viscosty gear oil.
I'm also tempted to rebuild the injectors since i have a bit of white smoke on startup, maybe clean the pre chambers as well. Can you get extra mpg by rebuilding the injectors? To the diesel guys out there, you are welcomed to chime in.
