[VAC] Re: Synthetic oil change intervals?

[NotoriousBuz@xxxxxxx]

Dan, When I wanted to extend the life of my new van (as I still do) the first 
thing I went looking for was synthetics. I spoke to more than a couple of 
mechanics that I trust for accurate opinions. This is what the general 
consensus was. 

#1. Do not use synthetics for first 20,000 miles. It was their feeling that 
until everything has had a chance to seat properly standard oils changed 
frequently will have less blow by. (yet the new Corvettes come from the 
factory with full pans of synthetic oil......humm?) (the dealer said warranty 
will stay in tact using synthetics)

#2. Synthetics last a long time yet still carry damaging contaminates. The 
standard oil filters do not filter out all the contaminates.

 Choice A. install some kind of super filter (These are available I do not 
know any more about them) or Choice B change the synthetic and filter more 
frequently. Meaning frequent oil changes at intervals that resemble the 
owners manual. At which point the standard oil still has useful life and is 
doing the job intended. When factoring in the $ 5-6 a qt. for synthetics at 
3000- 5000 mi. intervals, with little or no more engine protection at these 
intervals than standard oil gives, it was something I chose not to continue 
to do. Time will tell if my choice was correct. One thing I can say for sure 
if you change oil frequently you won't go wrong.

Singed, Your guess is as good as mine. J.L.#4361
