I have a couple of bullet cats still welded into the exhaust from my streetcar days and I don't particularly want to deal with the logistics of removing them. If I switch from the VR1 stuff I've been running to something like Redline's race oil (the red bottle, not the blue) would it kill the cats in short order?
Mitch - I'm gonna go out on a limb here and guess that you have a cat....hehe....just thought I'd save you the trouble :)
I dont think switching the oil to a race blend will impact the cats. That said, who cares if it did?
Now this ...
Great ...Quote:

The last thing you want to do is end up w/ a clogged cat.Quote:

It would really be better if you got rid of the cats...

I agree.Quote:

Only because you haven't driven at a track yet.Quote:

oh and ditch the cats, its not a street car so no need to have them anymore
I don't disagree that ditching the cats would be "better", it's simply a matter of time & priorities. Only so much time to work on the car and there are other things I need to get done. Loading the car on the trailer, taking a day off from work and hauling it to an exhaust shop to get all the pieces cut, fabbed, & welded in just isn't high on the list right now. It is on the list though...it'll get done this season just not this month.
The oil will be changed this month however. Any tech on the red bottle of Redline vs the blue bottle?
Motul 15/50-Patterson recommended it to me. What I have used and had analyzed and all was great. Plus it smells great.
And Glenn's problem isn't so much the going off as it is the coming back on.
I would have preferred he just went off track.
He might have if you hadn't cut him off.Quote:

What is everyone using for motor oil? My LS1 oil temperatures last summer have me concerned. (I know, I know, religion and politics aren't as bad as motor oil discussions!)Quote:

This Motul competition oil is used by Turner Motorsports but is $15/quart.
Pennzoil says that the American LeMans Ferraris use off the shelf 10-40W Ultra Euro Formula at about $8.50/quart. It will also be used by the Penske Indycars.
Casey - what Redline are you using?
Does anyone use Mobil 1? I've heard some talk about engine failures and that has me concerned since I am using it. Of course the '07 Mustang did 40 track days with it...
Any other suggestions?
And while I'm at it, how often to you change your oil and/or filter? I could get Ford Racing filters for the Mustang, any suggestions for the Camaro?
I usually change my oil twice a season. Using AMSOIL 25k Mile oil and filter in my 4.6L. I know the Mosty's do as well, and so do Darren and Mason I think...
Love in it Racing uses Mobile one and changes it 2-3 times a season since we do a lot of TWS PDS events too
I use M1 and have since 1998 in my 450rwhp/420rwtq LS1 Camaro. All my engine builders always ask what I'm using and tell me to keep using it.Quote:

I use an A/C filter. I change my oil every other event (overkill - I know). I change the filter then as well since it is pretty cheap.
I use M1 cause all but 1 track we run has a Walmart w/in 10 minutes and they always have it. This is in case I need to re-fill my system for whatever reason. This also prevents me from having to carry 8 qrts w/ me all the time. I do keep a couple inthe trailer all the time.
What is the temp your worried about? Do you have an oil cooler?
All of them? How many engines we talking here?Quote:

I have 11 quarts in the system (7qt pan, 3 qt accusump, and a cooler). I typically see 260F oil temps and only have it go higher if I happen to "cut the grass" and pack the front of the grille full of clover or whatever weed is in season.
I'm planning on running the whole season on the same oil and just keep an eye on the level. It takes a long time to get that many quarts dirty enough to block the filter. Also, the engine is tired so I don't feel like pampering it. (plus I'm lazy and the car is 45-minutes away so working on it takes planning).
Unless you are seeing 280+ I wouldn't worry about it.
I run Redline 15/50 in the blue bottle. Used to run Valvoline VR1 20/50 but typically see oil temps around 280-300 and just don't trust a non-synthetic oil at those temps. My motor was also built with fairly loose bearing clearance (.0025) and requires a heavier oil than a stock motor would. When I get around to ditching the cats, I'll switch to the red bottle of Redline.
I drain and refill the oil after two events and change the filter (Wix) after 4 events. Probably overkill but better than the other way around.
I use AmsOil 15w50 racing synthetic and change the oil every 3 events. My oil temp typically is around 270 in cooler weather and 290-300 in the hot months. I run an oil cooler.
I use the 300V competition 15/50. I get it from Alamo Motorsports because of Patterson. Search on FRRAX for oil threads as there are many that blame Mob 1 as it gets too thin to quick. Just ask Patterson as he used to change his Mob 1 during a race weekend. Yes its more expensive but I will run the Motul all season and then get it analyzed. So the cost difference isn't as big in the long term. I run a Mobil 1 M107 oil filter.Quote:

I do have an Al radiator and external oil cooler. The temps were 215 water and 265 oil at TWS last August IIRC.
A.J. at PST was surprised at the temps, he said that the oil cooler was "sized" properly (for the HP maybe?)
I'll pay more attention at TWS this month.
265? You got nothing to worry about.
