Why do you suggest using Pennzoil or non-synthetic Mobile oil in the case of a leak?I'd use Mobile1 synthetic 5w30 for motor oil, unless it leaks oil... in which case I would put Pennzoil or non-synthetic Mobile oil in it. I would not use a FRAM filter - they have paper and glue holding things in place inside them according to the parts store guy. I would use a K&N filter - they are well made and have a nut on top so you can remove them with a normal wrench. I'd put mobile1 synthetic 75w80 in the transmission.
Because synthetic oil is expensive and not worth it if it's all just going to leak outWhy do you suggest using Pennzoil or non-synthetic Mobile oil in the case of a leak?
I have been using Kendal Synthetic blend getting oil changes done at Firestone and have been noticing the oil burning up quickly.I checked my car for leaks with cardboard under the engine and didn't find any.
An oil stabilizer would help in both cases.Because synthetic oil is expensive and not worth it if it's all just going to leak out
Burning oil is a whole different matter than leaking oil. Burning means it's getting into the combustion chamber, which generally means piston rings are getting worn out. Using slightly thicker oil or thickening oil treatment sometimes helps with oil burning since it's harder for it to seep past the piston rings when the engine is hot.
