I must add that the "shrinkage"-problem used to be! They've worked on the oil, so the problem shouldn't be there anymore. > My recommendation is don't switch from dyno to synth on an older car, unless > you've rebuilt the engine, or are prepared to change several seals > (particularly crank seals). I've used Mobil 1 fully synth for years now. On all the three Saab's I've had and never experienced leak prob's. First Saab was a 99 with over 300k km, the second was an '85 900 T16 with over 200k km and my current 9000 with 250k km on the clock... Cheers!
