It was my understanding, though, synthetics leak more than mineral based oil's, hence older gaskets on older cars might spring more of a leak than regular oil?
: I researched this topic extensively and it revealed absolutely no down side to using synthetic engine oil. I run total synthetics in both my cars, engine, transmission, differential, power steering. I change engine oil every 6-8k and change the filter every 3k. I could go much longer but some habits are hard to break. I use Mobil 1 because it is available everywhere. I also use B&G 44K to clean the fuel/injector system and B&G MOA (motor oil additive) semi-annnually to keep the engine clean. I am a maintenance hound. The end result is I have no qualms about running to redline. Regards.
