what is/are opinions of oils- motor oil, engine sticker states 5W30, is it Brand loyaltiy ?? or what about "mixing" brands, I have been mixing Mobile1, Amsoil, and 'walmart' brands (walmart is made by Pennsoil) with a few Ounces of "MotorKote" and a few ounces of "Lucas" (Lucas oil stabilzer) -and been using 5W20, i run it 5-8000 miles and change the filter at about every 3000mi
(in my 1991 S10 4.3 i was getting like 28 mpg and I drove it like I stole it)
as for the rear end i am 'sold' on using synthetic - i used mobile1 last time but am thinking of switching to Amsoil with a few Ounces of MotorKote,
will the slipperiness of the synthetics make my limitd slip diff goof up?
as for the transfer case and transmission ?? ?? I dont even know what it calls for much less if there are synthetic compatibles ??
- I used Slick50 in my grease gun to grease all the Zerk fittings
