...for a flat tappet these days?? Got a new cam from Bullet with a moderate bee-hive spring but don't want to take any chances.

Thanks

I agree with Doc! Brad Penn,the "Green Oil"! Semi-synthetic,and good amount of zinc and phosphorous for flat tappets to survive! RandyB.

I have use the rotella 15-40 for the last 3 years..

I forget the hi-zinc code .. but the last time I checked a couple of stores ..... like Menards .... they had-it in Rotella.

Isn't that Brad Penn stuff real pricey ?

NAPA sells Valvoline NFS (Not for Street Use) Racing oil. It is the best I have found. Reasonable too.

i run mobil 1 10 w 30

what makes it NFS

marketing...same as most of the other "wiz-bang" oils. save your money, get educated about oil. i learned a little working in the lubes service center for a well known refiner

nfs has 1400 ppm zinc same as their regular racing oil and i believe the same (or close enough) to the shell oil mentioned

I was under the impression that the Rotella(which is a very good oil)had lowered zinc content for emissions!???

anyone ever heard of the rottella containing a lot of ASH? and leaving these deposits in the chamber?

i'm not advocating any particular oil, or slamming any. there's just a TON of marketing that goes on in the lubrication business. i don't claim to be any expert but i saw this FIRST hand and was somewhat shocked at the time. lubricants have to meet certain specifications imposed by both the government and API. if an oil has a given certification it must meet the specifications for that certification. not all oils had their ZDDP levels reduced the same amount depending on their rating. for the most part all oils had to reduce their content of certain additives. to make up for this they modified their additive packages in an effort to offset the loss of the restricted ones. below is a link to little info from an article. the link i posted to the BITOG is probably the best place to become somewhat educated about lubricants. afaik the shell turbo t is still around 1400ppm

I like the Rotella 15-40 with a bit quart of Lucas. I pick it up at Advance and use these $10 off $25 coupons.

I've run the 15/40 for years no problem, this year i want to try a 10/30 so going with Brad Penn

The newer Rotella is not the same as the old stuff.

Z-Alt Musclecar Oil is very good also.
