Amsoil ACD 10w30/30 oil in gasoline engine questio

ACD is about $5/gallon cheaper than their gasser version of 10W30 too. It's one of my favorites and it is loaded up with old school AW additives. Last I heard from tech services it was around 1300 ppm of Zinc.
 
I'm going to try it. My engine + filter holds 4.6 qts it says. I have 2 qts of Amsoil ATM 10w30 oil. If I buy a gallon of the ACD 30, and use a half qurtt of ATM oil to fill it all the way, am I going to have any issues?
 
I would think not. You will just be diluting your Z/P content down a bit and adding a touch of FM's to the mix, but I wouldn't be concerned with any compatibility issues. This product is awesome for 10-15k drains even when in severe service.
 
Yeah, it looks pretty darn good to me. I am running 0w30 now. My engine actually calls for 5w20 normally for 100f and down, or 10w30 from 0f on up. And then states it states 5w20 is recommend for optimal fuel economy and cold starting. I does not get THAT hot here in the Detroit area, but I normally drive the car from say April or so until November or whenever winter comes around. I think I should be ok?
 
I think it's one of the best oils Amsoil makes. A definite 'sleeper' oil at the price point its sold at....

Or, I also have Amsoil WCT 10w30 4stroke Marine which is a SL, and according to Amsoils has a Zddp of 1300ppm.

I wonder how that marine 10w30 would do in there...

I've often wondered this also, but given the ACD value/$ why look elsewhere.

FYI:I've run ACD to over 7K miles

Simply because that way I only have to purchase 1 Gallon, instead of 2 gallons and put 3.5 of it on the shelf. I have (2) extra qts of the ATM 10w30, and I have a entire case of the WCT Marine 10w30 (for my boat) on the shelf...

I saw that you may have had pumpability issues with the ACD in 30F. What makes you think that? I'm only asking because I put it in the freezer for 24 hours before I put it in my car and it sloshed around fine. I've run it down to about the same temp too and no issues, the oil pressure light seems to go off in the same amount of time and no noises.
 
Heck run the WCT then! Did you look at the NOACK on that oil...it's crazy. You could run your car and boat on the same oil and consolidate inventory. ACD is a good price, but there's no need for you to have 2 separate oils in stock that are 10W30.
 
I see that. I guess I never thought about using it my car because it is marine oil?? Any reason not to use it in a car engine?

That was in my younger dumber BITOG days. I think the car raced up to a given rpm and then dropped off and back up, so I panicked.... 8)

Gotcha! Even though according to it's specs I knew it should do fine, I had to put mine in the freezer to get a visual on it before putting it in the car for the winter.
 
From a wear control stand-point I would see no reason not to run it. Now the TBN is a little lighter than their ATM or ACD, but I'd assume that you could get 7-10k miles out of it without it stretching its legs too far.
 
Way to reign it in LargeCarMan. The current .pdf states 2x drain interval up to 15,000 miles for gassers. Gasoline Engine Service Intervals will have to be capped there. Assuming your oil computer reminder comes on at 8,00 miles then don't violate this language or else the all-be-it denos in Superior will not honor anything exceeding my first bullet point while following the new ACD recommendations...this is a difference from prior to the launch of DEO/DME when they had long stated the 15,000 miles or one year, whichever comes first in mechanically sound gas engines (for at least 5 years prior).

• Oil drain intervals may be extended up to two times (2X)
the OEM* recommended drain interval (not to exceed
15,000 miles without oil analysis) or one year, whichever
comes first.
*OEM = Original Equipment Manufacturer

The 3x stuff is only mentioned in DEO and DME at this point, but yes I am assuming some of the Amsoil dealers have also provided an inconsistent message to their customers about this. Change has to be really hard for Amsoil to complete -considering their dealer base is so variable in terms of follow up training and not knowing if the dealers are reading the info on their excellent website (heck we have a 74 year old guy who's an outstanding spokesman still telling folks to run AMO in EVERYTHING here in northern Colorado). All and all though I can say that no oil provider provides as much change control info as Amsoil that is readily accessible to the general public. Now Schaeffer folks do provide rocking specs, but IMHO Amsoil has them beat in openly printing changes for dissemination.
 
Indeed - the 3X for diesels came out to simplify things.

3X OEM - 50K miles/600 hours - 1 year whichever comes first. For all diesels when the oil in question is recommended.
 
Been thinking about trying this oil in my 7.3L. Since the 7.3L and 6.0L shear the 15W-40 and 5W-40 oils down over time to or close to a 30wt, and no further... Why not just start with a 30wt? Esp for the winter months.

What do you all think?
