Nothing burns my cheese like 3000 mile synthetic oil changers...   I run mobil1 or castrol in my 225,000 mile trac since new, and go 15k between changes. still runs like a top. I did not do UOA, but my job used to involve oil analysis, and what works and what doesn't, as well as what affect oil longevity. We used the number of hours on the engine to gage change intervals. One of the engineers really had it out for anything pennsylvania based, because of the sulfur content of the stock. My 1990 aerostar got new dino oil every 7500 miles, for over 230,000 miles, still ran like new. Wish i cold say the same for the body....</p></blockquote><p></p>
