Thanks for everyones input.
What synthetic 10W-30 oil has at least 1200-1300 ppm of ZDDP, is available locally, and does not cost an arm and a leg as some of the "speciality" oils do?
With an OCI of 3000 miles or less, (twice a year, before and after storage), how much increased engine wear am I looking at by using VR-1 Valvoline instead of synthetic? If VR1 dino oil will protect my engine to 1000000 miles, what would synthetic do for it? I am asking because I know people with similar driving habits that tout their $7.00-$15.00 a quart oil as being the ultimate. To me, without tangible proof, and I don't mean the 3, 4, or 5 ball test or whatever they are using now, I think it is all hype.
People tend to blindly equate price with performance. That is why so many street rodders buy "racing parts", because if it is good for racers, it must be good for my street car. I have seen many cases where expensive racing parts make for a lousy street car.
Using oil that costs over $4.00 a quart more than what I am using now ($24.00 more per OC), over 30 years (90,000 more miles)
will cost me an additional $1340. That will pay for an engine overhaul, if needed.
