Ive been part of this forum for years. I know oil is not a very fun topic around here. Of course ive done searches but id like input on which oil with higher ZDDP for the street. i specify street because of what ive read and can understand, too high of ZDDP may not necessarily be a good thing. Plus changing oil out 500-1000miles. My car will most likely never see the track. By some chance it does, a few passes and/or laps at most. I do have high flow cats that have been on the car about 3 years. I also ask because it would be nice to purchase somthing local instead of having to order oil for changes every 500-3k mi(pending amount of ZDDP)

Used to use Mobil 0-40 and rebuilt my 416 after 7 years and it looked flawless inside. I just recently switched to Mobil 0-50 racing because it has a 1850 ppm of zinc compared to the 900 the 0-40 has.

Thats swesome! However although cleaniness is good thing, one can have a clean motor and still not have the proper protecion required. See thats why i asked the question. Ive come across a few threads where people have stated Mobil 0W-40 has 1100ppm vs the rest of their oils which appears to be anywhere from 800-900ppm. Is it safe to run a conventional racing oil for common use in the street? high ZDDP is what you want, sure, but with that Mobil 0-50 how often are you having to change your oil?

VGLNTE1

I dunno. Depends what I do. If it's on track for a couple days I change it. Other then that, once a year. The car only sees about 1000 miles a year. The 900 i got from mobiles website. I think no matter what oil you run it needs changed at the same time. No one is going to wait the 15000 miles it takes for synthetic to break down. You change to get rid of all the particulates in the oil. I'd say 5-7000

im sorry. I didnt mean to ask about an oil to last nearly that long. Its just what ive read, extreme high zinc and phosphorus require very frequent oil changes. My car will definitely see more than a 1000mi a year. I live in florida and even though its no longer a daily, im not afraid to hop in and drive it 3-4 times a week.

Correct me if wrong, but aren't the more frequent changes are due to less detergents being in oils with high Zinc and Phosphorus.

I run 20w-50 VR1 (recommended by my engine builder) and change it either after an outing at the strip or as soon as I start to see some dis-colorization in the oil (which is usually less than 1500 miles).

If really have to change the oil that much, i will. I just like knowing and hearing all sides of the debate. I will call again just to confirm, but a rep from TSP (where the engine was built) did say VR1. Though he said 10-40 and they dont produce a 10-40. They have a straight SAE 40, which isnt the same??? Im really curious though about how long a street driven stroker will last with a conventional racing oil, vs a synthetic. I did find this....read 5.2

Also check into the Joe Gibbs LS30 oil that is what my engine builder stated to use in my 408CI.

I also run an LS3 based 416 and after having oil issues at the track I run Mobil 1 0-50 Racing Oil. I usually only track the car 5-6 times in Phx Oct-April and may change that oil 3 times during that time frame.

During the other times of the year I may run it on the street 3-4000 miles top and then I'll just run Mobil 1 20-50 and change it back to the race oil before tracking in the fall.

ZZ06

I very well may end up with that choice. I just wish i could get somthing of this caliber locally. Napa, adv auto, oreilys

Call TSP for clarification. They know how it was clearanced and what oil it's setup for.

I have a 650 hp 406 SBC in my drag car. I switched to Mobil 1 and Lucas stabilizer 5 years ago. I run the oil all season, and on winter tear downs, my engine is in great shape. I use 10w40 and the lucas without any problems. I used to change oil after 70 1/8 mile passes when I used dino oil. I also run E85 fuel and my engines are very clean on tear downs now. May not even do a tear down this year, as we haven't been out much this season.

ZZ06

Spoke with a gentleman yesterday and he said Joe gibbs LS30 or for local, im almost certain he said VR 10-40? Vavoline doesnt make a 10W-40. They make a SAE 40 but isnt there a difference????

ONE BMF

Been running RP long before i read this and a few big top tier oil manufacturers refused to participate. You'll know them when you don't see them. I now run RP HPS 5w30. The proof is in the pudding.It has the best film shear strength and thats what oil is all about.I'm quite confident that RP won't fail me. Read this link and decide for yourself what you want your engine bathed in.http://www.animegame.com/cars/Oil%20Tests.pdf

Yes they are different do NOT use SAE40 in your motor. I'm not sure what all is in the VR1 line. Tell them to send you what they recommend, then you'll know.

I have been running mobil 1 15w50 in my car since 2007. I recently last year switched to Pennzoil ultra 10W-30 since I got a deal on it. About 2 years ago my engine was torn down to fix a failed lifter and cam. The rings and bearings looked perfect in it. I change my oil every 10k miles or once a year.

ZZ06

15w-50 sounds good for the track, but all the time? Is your car stock? I wouldnt be asking this question for a stock or NEAR stock car. Once the cam, springs, etc. have been changed, the heat and pressures change as well. I ran pennzoil ultra in my car for 2+ years with a TSP 233/239 cam. I ended up with a few lifters wiping out that cam with that particular oil in the pan. Coincidence?? perhaps...but after some responses to this thread, ive done some heavy searching. For my new motor, even though it will only see street use, i dont think mobil 5w30- or pennzoil ultra 5-30 would be an ideal choice. i think im going to just order the Joe Gibbs for oil changes.

It is far from stock. The car is a 383 stroker with a 200 shot direct port on top of that. I use to daily drive the car until about a year and a half ago when I stopped. I use to also do a lot of racing on the weekends. As for my failure it was created by a mushrooming valve stem tip. That created lash in the rocker, which cause the lifter so flake some metal off the roller and mess up the cam lobe. It was only on one cylinder. While I was having all that fixed we re-ringed the engine and replaced the bearings. I do not have any pictures of them, but they were all perfect with no major wear.

I have a gen1 434 stroker, solid roller cam, about 550hp. ran a D1sc for 2yrs w/ 14# of boost in a 37 Plymouth truck streetrod and ran VR1 20w50 race oil from when the motor was built. Motor is 5 years old ~ 15000miles on it.

the motor is very clean, I cut open filters to check for debri and strange stuff

I have driven in all types of conditions rain, traffic jams, on the interstate cruising at 80mph for several hours

I buy the VR1 by the case from advanced when the put it on sale twice a year
I will be putting it my 2000 when I change the oil the first time, I just got this car.
