other than oil change

So we all clearly change our oil that is a must... Do any of you add engine cleaner before putting new oil? Or do you guys and gals add the fuel cleaner every 3k to 5k miles? if not do any of you do anything special that you can share with me and the rest of the tw?

 

no fancy stuff. I don't add anything to oil/gas.

 

Yes chevron fuel system cleaner once a year works very good

Also change your rear diff oil every 30,000 miles

I change my spark plugs every 30,000 miles also
