Quote from JohnZ

The "diesel oils" have also been affected recently. The API-spec "CI-4" diesel oil (which has a very high level of ZDDP) has been around for a long time (Shell Rotella, Mobil Delvac, etc.). However, the new EPA Tier II Bin 5 diesel emission requirements that go into effect next year require the use of catalytic converters and particulate traps, which are "poisoned" by the high level of ZDDP in the CI-4 diesel oil, so there's a NEW diesel oil, API spec "CJ-4", with a much-reduced level of ZDDP, intended for use with the new low-sulfur diesel fuels in the 2008 Tier II-regulated diesel engines.

CI-4 diesel oil offers better protection for sliding elements than the new ZDDP-reduced CJ-4 diesel oil; diesel oil used to be diesel oil, but now there are two DIFFERENT diesel oils.

Frank, I think there is definitely a market for it at that price. Some education would have to be delivered to help create demand for the product. Not everybody is aware of all the re-formulation going on; Rotella and other diesel formulas used to be "the answer" but now maybe not so much..

The whole thing sucks. We're trying to preserve pieces of history here, and the government (in their infinate wizdumb) wants to rid us of everything needed to preserve the past!

Uh-Oh, did I just make a political post?????

Verne,
I think you can rail against the generic government, as long as it isn't personalized with "damned liberals" or "stupid evil Bush".

I too have read that the amount of zinc (sulfated ash) content in oil will go down in diesel oils in the near future. It is unfortunate because Rotella is cheap and readily available. I use Rotella in my 'Cuda now because the 340 was built back in 1980. At the time it was built, had the largest hydraulic flat tappet purple cam available installed, so the big springs are hard on the cam and lifters due to a tight 108 LSA and a lift over .500". I guess that if we have to go back to conventional oils, then a camshaft/engine break-in lubricant will have to be added at every oil change. One of the articles I read recommended this. The author said he had been doing it for years. When I was at a super wal-mart the other day, I noticed an oil forumulated for vehicles made previous to 1988. I believe it was one of their house brands. Does anyone have any info on this oil? It was pretty cheap too.

Hi all. I saw this product being discussed over at another board.

This is precisely the same info I have gleaned as not only do I run Rotella T in all my three Olds W cars, I also have an old Ford PSD with 200k miles and hoping for 500k. It's had a steady diet of Rotella T CI-4 forever. Rule of thumb is if you see anything on there about CJ-4, it's the new lower zinc formulation.

The only way to get that now is in the Synthetic Rotella T which still seems to be in the CI-4 category everywhere around here. That stuff is expensive when you consider 14 quarts every 3000 miles. The small extra cost per year in the muscle cars is no biggee.

Oh yeah, the Citgo diesel oil here at Murrays is still CI-4. I'll park everything before I use anything Citgo. And yup, that's a political statement.

I think a good formulated oil at $4.00 a quart would be great. That's bout what I was paying for the old Rotella T CI-4 and CI-4 Plus.

I agree wholeheartedly with your political statement on Citgo.

Thanks for all the response. All of it is appreciated. Understandably, consumer education is critical in this endeavor. All the additives on the market currently seem to meet our needs at this time, but my approach is completely different. In these changing times just about every lubricant, as well as gasoline, requires some sort of additive to maintain the similar levels of performance and durability that we expect from our cars. It appears that they are no longer optional, all conceived, in my opinion, to compensate for already inadequate products we all purchase. Some European manufacturers have taken the vintage oil situation to the next level by producing a more than adequate performance and protection oil for both their performance and antique automobiles. It would be simple to buy and market these products in the U.S., but unfortunately, due to the weak dollar, and higher costs of petroleum, doing so would result in a quart price of about $12.00 or more. Through continual discussions with ILC Spectro, a new additive package possibly called "Zincare" (trademark pending), blended with the best available base stock will produce a product that both protects and performs under the most severe of conditions. We all use our vintage cars differently, some for daily use, some for racing, and some strictly for show duty, some stay in long-time storage. Our new product is engineered to address all of these situations with no compromise. Hopefully, the perfect blend can be found soon, so we can continue with testing prior to sale. Thanks for the continued support. Regards -- Frank
