Having problems with your 1994 Chevrolet K1500 ?
What oil to use in a 1994 k1500 z71 - 1994 Chevrolet K1500
I cant be sure but . if you look at your oil refill cap on the valve cover where i think it is. it is written right on the cap as to what the manufactorer says to use..i think it says 5w30. me personally i live where we have pretty good winters.good meaning bad feet not inches. i use 10w30 in the winter you dont want an oil that is to thick when it is cold in the winter.. and in the summer i use 10w40.. and once again, you dont want an oil that will become to thin with summer heat. but the worse part is your oil will break down because of road heat.hence the heavier viscosity in summer
