deposits buildup and why I'm switching to synthetic

My 2 cents...synthetics seem to be more viscous/liquid right? So they sneak past hardened seals easier. Wether it be oil pan, valve covers, cam orings, front main seal and oring, and lastly the valve stem seals which harden from many miles. You will get leaks sooner. I like the synthetics benefits and can fix my leaks easy enough. Ex. my old 90 integra added Redline as soon as I could find a dealer that sold it. After the first oil change noticed better gas mileage, quiter and smoother running all around especially above 6K RPM. 2nd oil change 4k later synthetic oil still looked new. After going in to adjust the valves it was clean as a whistle what I could see in the top end. My old 1997 Outback I went to Redline right off the bat, mostly chasing down better MPG, got a few leaks but 10K later had them all done soon with t-belt job, spotless valve covers. No oil leaks after. Now 92 Turbo Legacy is getting it once the block gets a second flush. Already tackled all the leaks. Well maybe that was 20 bucks worth. http://www.redlineoil.com/
