Thanks for the replies. It was my understanding that Rotella was reformulated in the last year with lower ZDDP levels? Same time it got the T6 label? Ok so lay it on me what kind of ZDDP levels does AMO 10w40 have? How does that compare to DEO? The 5weights seem like a good idea because it can...

Does anyone know what the real world differences between the DEO and AFL? AFL is the European car formula and DEO is a diesel oil. It looks like DEO is thicker and has more additives. Also if anyone has any info on ZDDP levels that would be helpful. Im looking for a universal replacement for my...

As another possible return location you could look at the turbo oil return line. There is usually a way to T into it without to much work.

Hey Gary, most people can't see much of that TDR thread. A while back they changed it so non-members can't see post more than five days old. Too bad there's a lot of good discussion in that thread.

Storage is a big issue. That is the one reason why I don't run amsoil 100:1 at that ratio. Its good oil but it won't protect during storage so I mix at 40:1 just like any other oil. I was running amsoil in my snowmobile, but now I'm rethinking that. I could deal with the off season storage, but...

This is not my info. I don't really have an opinion one way or another. I just thought it was and interesting conversation. One oil is amsoil interceptor used on a snowmobile engine. Another engine was run on polaris blue a cheaper dino 2cycle. One crank is rusty the other isn't. Pics to...

This is a classic CYA situation. If ford allows the use of HDEOs in gas motors they run the risk of increased warranty problems. It could also be driven by the EPA requirement that all factory emissons systems be designed to operate within specs for 150k. In tests ford learned that they can't...

I may or may not have a coolant leak. If I do it's small and isn't causing extreme wear yet. The lab was very worried about the high lead indicating bearing wear but they said nothing about the sodium and potassium. I forgot to mention that I run leaded fuel from time to time. But considering...

I'm surprise blackstone flagged the sodium at only 10ppm. Valvoline uses lots of sodium as an antifoaming agent. Or... you could have coolant leak. s

I would start at 5k too. Then if things look good through UOA, step it up. The rotella syn is a group III syn but unlike the other "fake" syns it's price reflects it's quality. Rotella isn't trying to fool your average consumer into thinking their 5w-40 is a syn just like mobil 1. It has a good...

This oil was in service for about 9 months including winter storage. About two qts of make-up oil was added. 8 oz of valvoline synpower oil treatment was also added. This 302 dynoed at about 300hp and gets run in all conditions from winter hunting to high speed highway in 100 deg weather. There...

Thanks Terry your always a great help. I got the name zyline via word of mouth from my grandpa. I was wondering why all my searches were turning up nothing.

5w-40 would be fine at -20. I run 5w-40 year around and chose the oil for that reason. You could run 5w-30 in the winter and 10w-40 the rest of the year if you don't mine changing it more. Your leaks could get slightly worse with a group III syn, but nothing like a groupIV+. Group III is...

I have 450 gallons of 10-15 year old gas. I have run some of it in an old motor that I don't care about and had no problems. I would like to get it analyzed just so I know what it is. It has a preservative called zyline in it. Anybody know where I can get an analysis done. I don't think I could...

There should be other options on 12v cummins. I belive there are two spots to return oil to. They are on the right side below the turbo. One is used by the turbo for a return. You could T into that.
