I've read on a few threads people are overfillign their LT1's with a quart or so... Is this the recommended procedure?!? Wouldn't GM have thought of these kinda events when they set the oil level??

Thanks for your thoughts!

I would be very careful running that on track without an Accusump. I put a canton pan on mine, and was still seeing pressure drops. Got a three quart accusump that solved the problem. I have talked to a lot of LT1 people who have spun bearings due to oil starvation.

this isnt a full on track car.. it'll probably see this event coming up on friday and maybe one other this year.. Is there someway I can mitigate the issue without spending a ton of money!?!? will the extra quart cover me for these few events?

I have been over-filling my LT4 by a quart with no problems. I want an Accusump, but it's not in the budget at the moment.

I overfill my LT1 by about a half quart, 292 RWHP, use Redline 10W-40, no accusump, no oil cooler(285-290 deg F oil temps at the track), factory pan, 5800 redline, 14-16 track hours a year plus driving to and from the track(about 3,000 miles), change oil once a year(I do used oil analysis to monitor engine wear), R compound tires with 1.2 + lateral G's measured on a Gtech, lifetime track hours: 60-80 hours. ZERO mechanical engine problems. LT1 is a pretty tough engine.

I would put the extra oil in it...and keep your eye on the oil pressure gauge-especially in the carousel. If you see it dipping, you are shortenining the life of your engine. Some people don't have problems, like the guy above who only changes his oil once per year

See you Friday at the track.

No, the oil level would be set for the 99.9% of the LT-1s that never see a closed track course. The racing most of these engines ever see is drag racing, and even that number is pretty small.

with Tim's comments above.

Have fun!

I always go 1/2 qt to a full qt over on my LT4. Change oil once a season with 15w-50. That's about 1100-1500 track miles per season.
I have Blackstone anaylize the oil, and they say it's perfect.

This was a short season for me, I normally get 2000 track miles on a good seaon
oh yeah, no oil cooler for me. The motor is bone stock, and I won't touch it.

There is so much makeup oil going in there, it's fine.

I would start with the Canton Roadrace oil pan, It will help PREVENT oil starvation while the Accusump only kicks in when the oil pressure drops.
The pan (Part #15-240T I think) is less than $300, & that is cheap insurance that would not hurt "the budget" nearly as bad as a blown engine.

I always ran an extra quart of oil in my LSX and LTx motors. I spun a main bearing this summer in my LTX motor due to oil starvation, even with the extra quart. Sydney004 is doing something right if he's driving that much and not having any issues.

upstate NY, did you get oil starvation at WGI. possibly in the toe, or outter loop ?

I have never had a problem with my LT4, but I can't watch the guage when I'm lapping. I always want to watch the guage, but I can't seem to glance down , except when on the straights....

I run 1/2 to 1 qt over in my LT1 with no issues so far (Summit Point Jefferson, Road Atlanta, let you know after next weekend about Roebling Rd)

Axelrod

Seriously, oil starvation issues in the LT1 are more serious than the LT/LS motors. Hard braking in an LT1 is enough to cause oil starvation from the pickup. Even with a half a qt over-fill.

Ask me how I know.

sothpaw2

Do you feel 1/2 qt over is enough for the LS1 or LS6? Say for 5-10 hours on track per year.

H82GOSLW

Yes, car was shot after running at Watkins Glen. Yeah....it's kind of hard to glance down at the oil pressure gauge when you're pushing 130mph through the Esses Only time I look down at any gauges is in the back straight after the Esses, front straight, and maybe the Carousel after the Bus Stop. That place is awesome!

Polyol Ester based oils tend to have stronger oil film strength and affinity to the lubricated surfaces and may be beneficial in applications like the LTX engines where consistent oil pressure may be problematic. Matching the proper viscosity for the intended application is important and that is where used oil analysis is very helpful. Terry Dyson at

assisted me in selecting the lubricant. On top of all that I have my fingers crossed that it does not blow up at Laguna Seca next month.
