But would you do it? Would you dump Super Tech 5w-20 conventional into that sump or would YOU pay for better? Im not asking if I can do it Im asking if you guys would do that?
It depends on the OCI and driving conditions
For a short OCI of 5k or less, or if it has the IOLM, and I needed the absolute cheapest oil with no rebates, I'd totally use Smitty's (which often costs less than Walmart ST).
For a longer OCI with no IOLM, or for fans of rebates which can make synthetic equal or cheaper than dino, then I'd use synthetic. Also, if the particular engine is a known sludger (Toyota's 1MZ, VW/Audi 1.8T, etc), then synthetic is a must.
Does that engine have any known issues in regards to sludge, or anything that would severely impact oil life? Does your car have the IOLM? Do you plan on modifying it?
