Because I have a tired old Model A engine (no oil filter) and because I can't find 40 or 50 weight NON-DETERGENT motor oil in Miami, Fla...I am mixing a can of STP with the 30 weight non-detergent oil to thicken it up. My question is.....am I defeating the purpose with the STP? Does the STP act like a DETERGENT?Any other suggestions for an additive (to make the oil thicker/heavier)? |
