BG 20-50 Racing Oil

If you use that oil, use a heater with it as well. A 50 weight @ 212 degree's is thinner that a 0 weight @ 75 degree's.

I used to run 50 w in my 340 dart some years ago . now that I have a new motor 416 storker to go down in it before I start it up what would be a good lifeable oil to run in it. just asking???

Larry, I'm not a Mopar guy but they are all engine's. Alan's advice is sound. I said what I did because a 20-50 was a popular oil for the roundy guy's but those motor's spend some time getting warm & buy the time the race is hot & heavy, the oil is @ 20 centistokes. Not so much in our drag racing. (unless it's a street/strip car driven to the track) I spent some time reading here:

Then I put a wide sweep oil pressure gage in my daily driver (95 escort w/195,000 miles) & started playing with grade's. I know my racecar has different needs, but it's interesting.

Thanks Alan and to all that replied, I've never used anything else but Valvoline 10/30. I'll keep the BG far away from the Camaro.

thanks... I like lucas oil that's what I run in my old dart and what I was going to run in the new car and engine...the reason I use lucas is because I had some work done on the last motor an when the guy I had doing the work ask what kind of oil I was using I said lucas he said that the bearing had little or no wear in them . but I do use Valvoline in my truck and my wife car big fan of it. what about the VR1 from Valvoline??? I have heard that some like it for a race oil and a good break in oil. I don't know how true that is.

As outlined, while the BG 20w-50 is a higher viscosity than needed for drag racing, especially for Stock, it may at least have higher levels of zinc & phosphorous most people recommend for older performance & race applications, as well as break-in. But you have to do some research to know which oils still have higher levels. "Shelf" oils for newer cars and diesels have had a lot removed and even some racing oils don't emphasize the ppm content.

It's explained a bit more in this Amsoil bulletin:

Of course, if you have Schubeck/Smith lifters, it isn't as critical.
