Ah ok, that's what I meant I was just wrong lol. Good info, Mr. Lettuce.

Anytime 94-94. This is where I stole my info: http://www.ihpartsamerica.com/forums...html#post64570 And yes I did read all of it!

None of the ones suggested so far as your threads are metric and the newer ones are standard. It's common practice to chenge the threaded nipple with one from 91 on so you can use the later filters.

Whoops I didn't even see that post...

Yes take cruiser's advice and change out that part. All of the good filters in North America are threaded 3/4-16

Just to further expand on this- (Which I discovered from the stroker forum as all manufactures of strokers demand that you use a zinc based oil or a zinc additive to maintain your warranty) Our Jeeps (and plenty of other cars) have what is called a flat tappet camshaft. All engines with such a camshaft should have adequate zinc in their oil as the zinc adds another layer of protection for the high pressures and tight tolerances that come with a flat tappet. In 2007 with new emission laws the amount of zinc in standard oil was cut drastically. It should not matter much to those of us with a well used engine as it has already been coated in zinc for quite awhile. On a rebuild/stroker etc. it is highly recommended to get a zinc additive or a oil that has adequate amounts of zinc in it.

I personally use Amsoil and will use the Amsoil "Z-rod" high zinc oil in my stroker. Nothing against Rotella, I have just always used Amsoil in everything with great results.

Heres a great high zinc oil list if anyone cares including ppm.

Not a waste at all-thanks for the link and your huge post in there! While I didn't read the internal links yet I will- I had no idea about zinc amounts until my stroker manufacture (Golen) educated me that I absolutely need to run a high zinc oil. In the setup instructions it says it like 15 times lol. So I ran to google and found out that its actually pretty important haha.

Yeah there's a picture of a Ford cam - flat-tappet design, same as our engines - run on API SN oil. It's not pretty.

i do believe that valvoline vr racing oil is high in zinc.. might be something to look at!

Sounds expensive... "racing" is not always a good idea

Ianf406

according to the corvette forum link I posted, the VR is rated at 1300-1400 ppm BUT it also says this "NOTE that there are some concerns with VR1 due to inconsistenttest results. Additionally, racing oils are not intended for extended (3,000+mile) change intervals nor start-and-stop cycles."

Some data in the first post of this thread: http://forums.rennlist.com/rennforum...acing-oil.html Comes in 10w30 and 20w50 only? lol

TBN of 8, for reference Rotella T6 is 10.6

"Racing" filters are high-flow and not actually designed to filter, so it's not surprising that a "racing" oil isn't supposed to last long.

For those Renix owners wanting the later model SAE oil filter nipple, you can grab them at the junkyard. You need a 15/16 to get it off the oil filter adapter.

Actually, the part is about $5 at the dealer.......

BlueRidgeMark

Hmmm... I'm guessing that means the junkyard price is probably anywhere from $3 to $10, and of course, it's always more convenient to go the junkyard than the dealer....



I think I know where I'd go if I needed one!

The Napa Gold 1515 is the same as a Wix 51515 but at a little over half the price.
