Valvoline Synpower results within>>
I don't abuse the car - but it does see the upper RPM range from time to time on the street. I've made a grand total of 12 passes at the track in 2.5 years of ownership. It gets oil and filter changes (Mobil-1 filters only) changes every 3,500 to 4,000 miles regardless - I just change oil regularly to make sure the oil is as fresh as can be.
When I did my cam swap, the oil pooled up in the head was very clean despite having been in there for almost 4K miles. The heads, rocker arms, pushrods, etc. were all very clean. This leads me to believe that the synthetic is doing its job and doing it well.
Under these circumstances, taking into account these rather vague variables, am I really getting much out of using sythetic versus dyno oil? Is it worth the extra $15-$20 every time I change my oil?

This bulletin I have in hand is printed by GM....right from their system. Part # 88894299 Ring kit, Piston qty 8
Labor Operation in warranty J1307 Piston, Rod and or rings replace both banks.
Roger, it's not BS what you heard. GM has finally addressed the problem as stated in the above release, take a look!! <img src="images/icons/wink.gif" border="0">
John, I will be sticking to it from here on out, I like the fact that when I jump on it, I don't see the oil pressure go down...as it sloshes back in the motor.

If I were to ever switch from Mobil 1 to another commercially available synthetic, it would most likely be Valvoline. The others don't appear to be very good at all (such as the Quaker State or Castrol synthetics for instance, both of which are junk)
<strong>what weights do they offer in the Valvoline Synpower?
I run the 15w50 Mobil 1 now but as of late seems to be lacking a bit</strong><hr></blockquote>
I've honestly only bought 5 and 10 W30, so I'm not sure what else they have. I'm pretty sure I've seen other weights on the shelf, but I don't remember what.
Basically, it all comes down to; Those who know, use Valvoline. <img src="images/icons/wink.gif" border="0">

I'm more inclined to spend the extra $20. I'm of the mindset that if you can afford a nice car, you can go an extra mile to take care of it...
The only reason why I'm thinking of switching is that some people have seen the oil consumption drop with the Valvoline & Royal Purple and I think that would be a worthwhile benefit.
Brad, didn't you go back to an oil change of Mobil1 and end up burning some oil before going back to Royal Purple.
Also, Tom Izzo at LS1Speed.com carries Royal Purple 5W-30 now and I just got 2 cases delivered today. <img src="images/icons/smile.gif" border="0">
I have checked the oil other times within my 3K intervals and have had to add one time 1 1/2 qts.
I changed to Synpower and my car has been to the track 3 times (made about 10 passes) has been on a long fast road trip (alot of hard accelerating in an Fbody caravn) has been dyno'd (3 WOT pulls) and I have not used any oil!! <img src="images/icons/grin.gif" border="0">
I have about 500 miles to go til its at the 3K change interval. My PSI is around 50 driving in 4th, 5th gears just cruising.....so that is good.
I am happy with it so far. I guess I am sticking to Synpower from now on.
Just thought I'd pass that info along.

When I get around to doing the PCV mod, I am reasonably certain it'll stop burning oil altogether. I am not sure, but I thought the 01/02's got upgraded piston rings to help alleviate the oil consumption problem. Somebody shed some light on that please, or tell me if what I heard is bullshit...
Yes, I also use SynPower (10W30). It’s really the best oil I’ve tried yet, and I tried a lot. My oil burning still isn’t gone completely, but this did reduce it. Also, doing the vertical PCV setup help too, but I can still see that it uses a little even with that.
Running my Metco breather seems to have all but cleared up my oil consumption issues. I think mine were mostly PCV related to begin with.
Personally I recommend a full synthetic, however if you want to go with a blend, you're better off mixing it yourself by buying 3 quarts of dino oil and 3 quarts of synthetic and mixing the two.
Moral of the story? I'll be sticking with synthetics, no matter how often I change oil.
