Hello,

In the past year or two I've been using 1 cup GM EOS (original formula) along with dino chevron 10w30 in my slant six but my stock is dwindling. This is my daily driver, not a very serious build, stock cam & valvetrain. However, I do like to stomp on it every now and then. Who wouldn't?

Thing is, I'd like my oil choice to be future-proof incase I do decide to get a differnet cam and stiffer springs.

I came across the article written by the corvair owner many of you seen that recommended CI-4 rated oil. Problem is, I can't find any 10w-30 HDEO CI-4 or otherwise on store shelves. 15w40 CJ-4 yes, Rotella Synth 5w-40 sure, 10w-30 no.

If I wanted to mail order, theres the Amsoil ACD but its awfully pricy.

Is this stuff special order through distributors only, or is it just not available and I should be spending my time finidng a better solution? I probably could get away with 15w40 in this fair California weather, but I'd rather stick to something thinner.
 
First, you're going to stuggle to find any HDEO in CI-4 anymore from (what I like to call) the big three; Delo, Delvac, Rotella. The CJ-4 is going to preside over all the sales; and why not? It's every bit as capable for nearly all applications. You can't find much, if any, SG or SH anymore either, but it's not of concern to the major oil companies, as they serve the masses and not the niches.

As far as brands in that grade, both Rotella and Devlac 1300 are available in 10w-30 are are fairly widely distributed. There are others, as you've mentioned, but these two are more prevelant in the lighter grade.

I run the Rotella year round, and I can routinely find the Rotella 10w-30 in my local farm supply Rural King store, in both quarts and gallons! I also see the Rotella at Menards year round in 15w40, but only the 10w-30 in the fall, for some reason. The Delvac is a bit more difficult, but not impossible to find, mostly at farm supply stores.

Most any AAP or AZ would order either for you at the shelf price, if not stocked. You just aren't likely to find them on the shelf, or on sale.

My local Murrays (part of the CSK kingdom) has Motorcraft HDMO 10w30 in quarts. I don't know if any of the CSK stores would also, but if Murrays has it maybe they can order it. Alternative is get any decent 10w30 and boost the zddp unless your vehicle specifically calls for HDMO. I'll sell ya my stash of CD2 High mileage additive cheap (buck a pint plus shipping) which has about 4000 ppm z and p, as I ran a VOA on it. I don't need the stuff, overstocked. Of course there's always Redline which has gobs of z, p, and moly, if the old slanter's seals can take it.
 
Ah wal-mart, forgot about their oil aisle.

If the HDEO I'm going to find is still going to be CJ-4, I'm not sure I see the point as I'd still have to add more zddp right? May as well stick with the SM and EOS combo I'm using now.
 
I live in Northern California and I have never seen it in stores; I havn't looked real hard but so far I have not seen it.

Soon I am going to have to get some for my Kubota and the dealers have it I believe. I have not read anything on this oil here but it should be good. No idea on cost.

Another thought is Ford dealers as they sometimes recommend 10 30. Motorcraft is good oil.

Look up an oil jobber in the phone book I get my Chevron products from the local jobber. I have purchased 10w-30 Delo 400 .
 
Walmart had 10w-30 rotella but cj-4.

Chevron supplier in phonebook had 10w-30 Delo 400 LE.

Waiting for a response from the shell supplier. Had 10w-30 Rotella CI-4 in a drum, need to see if they can order it in gallons/quarts.
 
Motorcraft makes a 10W30 that is expressly intended for the later 7.3, 6.0, & 6.4 diesel engines for winter use, last ones I saw were CI-4, seems to be a slow mover at most dealerships, if you have a Motorcraft distributor he should be able to order it for you. Why not 10W40, I used it in my old slant sixes years ago-those motors are nearly indestructible!!
 
Ford dealer had 5-40 synthetic and 15w40, says he hasn't heard of anyone doing 10w-30 in diesel. So unless I have a part number I won't get anywhere with them.

Going off the advice of that article by the corvair owner, says to keep the viscosity difference to 20-25 points. Plus I thought I remember reading elsewhere that -30 to -40 meant extra additives prone to sludge? At this point I'm not sure the viscosity maters as I can't find anything of reasonable quantity in ci-4.
 
5w40 RTS works well in a lot of vehicles. I just finished a run of it in my F250 with a 5.4. Great stuff, no consumption. I have purchased Rotella 10-30 at WM before. Any Shell jobber should be able to get it in gallons, or 5 gallon pails.
 
Yep, walmart had the 10w30 cj-4 @ $13.xx a gallon and the 5w40 synth at $19.xx a gallon.

Few calls to distributors - seems they can get cj-4 10w-30 but all cost more then walmart. Ci-4 doesn't look like its going to happen unles I happen to stumble upon some collecting dust on a shelf. I think the cj-4 is a fair compromise. At 1200ppm zinc spec that should accomodate flat tappets well without any additive.

If I can run the synth. at 6k+ miles OCI it would be even more economical then the hdeo rotella.
 
FWIW on its bottle, Rotella syn claims to be an SH, SG spec oil, although there have been posts saying that API does not certify this.

I don't know what your goal for phosphorus and zinc may be, but, if you go to the UOA, CJ-4's are running phosphorus in the 1200-1300 range and zinc in the 1200-1550 range. If your engine is well broken in and broken in easily/smoothly, your cam lobes and lifters should live long and prosper with those levels.

You can also go to a 10W-30 or 10W-40 Motorcycle oil and get even higher phosphorus and zinc, on the order of 1600, as well as a lot of other goodies, but, synthetic motorcycle oils are pricey. It is also worth looking at Valvoline dino motorcycle oils and also their dino race oils.

I had a 1972 Twister with the slant 6, automatic. I put well over 100,000 miles on it with Castrol 20W-50. One trip went from Ft Lauderdale, FL, the northern route, to San Diego CA, down the Baja strip, and back to Ft Lauderdale. Just over 7000 miles.
 
I vote for the ACD. Been running it year round now for most of the 71,000 miles on the TL. It's got all the Zinc you need, no VIIs, and it still flows better than most dino 10w-30s when cold.

What part of CA are you in?
 
Frank, where have you seen VOAs of CJ-4/SM HDEOs? I can't find anything. Despite all the chatter about lower Zn & Ph in the CJ-4/SM than the CI-4 PLUS, I haven't seen any data proving or disproving the speculation.

That being said I'm running Rotella-T 10W-30 in my 2002 Jeep Grand Cherokee 4.0L and Castrol Tection Extra 15w40 in my 520bhp 3000GT VR-4. Just looking for info since both of those are CJ-4/SM HDEOs.

Thanks.
