Re: Anyone using Valvolene VR1 racing oil?
I was gonna try and quote the various questions until there are TOO many. /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
1st, Tony spaketh:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:]Ed - are you talking about that oil additive you can buy at Advanced Auto parts stores?
Why do you think its needed in all our engines if we use Castrol 20W50? [/QUOTE]
Then fortunately Shawn spaketh (and THANKS, Shawn!!:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:]There have been several discussion concerning this problem on this very forum. Surprised you guys haven't read them. [/QUOTE]

Then sparkydave spaketh:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:]does the ZDDP mostly benefit the cams, [/QUOTE]
and Mac Townsend replied:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:]Yes, ZDDP is needed on a continual basis, beyond break in. [/QUOTE]
The sitution is that the OLD Castrol GTX 20W50 <span style='font-family: Comic Sans MS'><span style="color: #CC0000">HAD</span></span> the ZDDP
levels required for <u><span style="color: #3333FF">FLAT-TAPPET MOTORS</span></u>. The problem exists for even My 'Camino's 350. <u><span style="color: #3333FF">FLAT-TAPPETS</span></u>!!! The majority of oils we USED to be able to use now needs the additive(s). And Tony, with a NEW cam/flat-tappets you REALLY need it or your "breakin" will not really occur because the degrading of tappets STARTS as soon as motor starts. For NEW motors I prefer GM's EOS as it is a Assembly Lube with INCREASED ZDDP levels.
Vince, YOU STILL need it also. Miles IS miles with short trips WORSE!! And I really do not think it is "responsible" to change oil at 500 miles. Better twice a season with filters. If anybody is REALLY concerned with taking the BEST care of your motor then you should do a Lab Analysis with every change. Info IS amazing.
And I would never use a synthetic oil for break in. Maybe for a race motor but not a street motor.
