Valvaline 20/50 with a wix race filter. Not to stir the pot with a filter contraversy. Dont use fram filters for anything, not even your coffee!

We use conventional 10w40 for break in and run 5w-30 synthetic for racing and a napa gold filter - same as wix racing. There was an earlier post about fram filters. I would recommend checking the archives and reading that post before even considering running a fram filter. As far as synthetic vs conventional: synthetic is expensive, but I never met a racer that switched back to conventional after running synthetic.

Huh....Guess I been living under a rock and didn't know about Fram (the kind I usually buy). No wonder my engine guy gets weird about it. He always wants Wix now I know why.

I look at it like this-You spend say $4000 on your race engine, then you go down to Wal-Mart and buy the .88 cent a quart oil and put in it-I DON'T THINK SO-
I spend a lot of money on good synthetic motor oil and change my filter every race, I have my oil analyzed every 3 races to monitor engine and oil problems.
There is a lot of good oils out there and everybody has an opinion about each of them, I personally use Amsoil 20-50 racing oil with Carquest racing filter (made by Wix)

I have used Castor 20W 50 and Valvoline 20W50 with great success. As to what filter to run - Do NOT use a Fram filter and the reason why is that it does too good of a job and "could" impede oil flow to critical engine components. I run a sbc 355 and use an AC Delco 1218 filter and have never had any problems. I had to learn about oil starvation the hard way! Looking back at when I started I didn't even know about circle track oil pans - didn't take me long to figure that one out![IMG] I also agree with very frequent oil changes - Cheap insurance for a pricy investment in a motor. I change mine every other week.

Used to run whatever 20-50 was cheapest that week. And never had a problem running my motors for 3 seasons between rebuilds. Now I run Kendal GT 20-50 because my engine sponsor told me to. I have always ran a racing pan and changed oil every 2 shows. And I have always ran NAPA Gold 1061 (wix) not silver filters.

I have run with 20w50 valvoline vr (race) oil. I had used Royal Purple at one time, and even after reading not to use synthetics from Crower, and other sources with a hydraulic cams/lifters, I did so, and with not very good results. Wiped out a cam lobe. I know what a lot of the gear heads are going to say about this but if you think about what synthetic does cold, before it warms up, maybe Crower, etc are trying to tell the consumer something. I'm sure it has worked for others, but I have always had great luck with the valvoline vr 20w50, and I especially like the fact it has zddp(zinc) which helps with cushioning between journals, and bearings. I usually change oil after 2 races, and I use wix only.

I have run mobil-1 15-40 synthetic for a few years now and its well worth it.At tear down in the off season you can notice a signifigant differance in condition of the main and rod bearings with the synthetic oil.It sticks to parts better and does not break down in extreem conditions.
