Hi all, I have looked at this site here and there for the past few years and finally registered. It makes me happy to find others who care as much about their vehicles as I do. Of course I do have a question. I know I will get varying facts and opinions on this but here it goes...
I have a 1999 Mercury Grand Marquis that I purchased about 5 years ago with 125k miles. I have religiously used Motorcraft 5w30 synthetic blend and Motorcraft FL820S filters every 3000 miles. I recently discovered that Kendall GT1 blend 5w30 is basically the same oil. I plan on buying it by the case to save money over the Motorcraft oil. My question is this: I also have a 1992 Ford Tempo with 2.3L pushrod 4cyl / 5speed that I use as my daily driver. No short trips, but sometimes hard driving. I bought it at 52k miles and have used Castrol GTX 5w30 and Motorcraft FL1A every 3k miles. It now has 64k and the oil is perfectly clean. It doesn't seem to burn any, but leaks about half a quart between changes (minor head gasket and oil pan external leaks) It is driven enough that at 3k intervals, I change the oil every 4 months or so. I plan on keeping this Tempo forever and I am also set in my ways when it comes to 3000 mile OC intervals, so between Castrol GTX conventional and Kendall GT1 blend, what would you all recommend? Cost difference isn't a factor to me. I just want minimum wear. I have heard GTX has a good amount of ZDDP for reduced camshaft wear of flat tappet cams, but does that make it any better than the Kendall in this situation?
Thanks!
