best oil to use
I know this thread has probably been hashed out multiple times.
509 Mag MPI with a vortec.
I currently am running the mobile 1 15w50. Is this just fine or should I be using something like VR1 racing oil with more ZDDP?
Also thoughts on straight 50 weight for summer in florida.

Oil of choice here at OSO is:
Mobil 1 15-W50
and
Valvoline VR1 20W50
So, you have that going for you and really no fights over oil here in say last 5-8yrs or more ?

Amsoil Racing 15w-50 is also a good choice.

I heard that Brad Penn was bought out and not as good anymore. Summit doesn’t sell it any longer.
The general consensus over the years seems to be changing it often is more important than any specific brand itself.

I run straight Slick 50 with a ZMax/Lucas oil treatment stack. Top off with some Motor Honey as needed.
I know a guy that was running 5W30 in his warmed over 500 EFI's because "that's what the builder told me to run". You can't make this stuff up. And no, the builder didn't tell him to run 5W30. He couldn't find 20W50 on the shelf of the brand he was told to use so he just went with 5W30.

I've been running straight HD 40W in Texas for years with no issues. Seems to help keep oil press up when oil gets hot (i.e. 220+ degs)
As for the brand to use, everyone has their own opinion. I personally have never seen an eng fail solely due to wrong brand of oil. IMHO, once past break-in, just pick your favorite flavor and stick with it.

IMO the most important thing to get right first is the correct grade (weight) for the climate you operate in. As an example it pi**es me off no end to see that the dealer/service shop for my pop's car uses 5-30w coz they buy it cheapo in 100 gallon drums when the owners manual clearly calls for 20-50w in my climate .
