Edelbrock Oil?

[MaineMan87]

I apologize for making another oil thread, but I searched and searched and could not find anything regarding Edelbrock oil in AMC 304 CJ's. I bought a 74 CJ5 this week and am preparing to change all of the fluids in it over the next week. I have read the FSM and it recommends 10w30 or 10w40. This is a summer toy for me up in Maine, so it will see mostly 70-90 degree weather, so I am leaning towards the 10w40. I've read the posts regarding getting an oil with more zinc in it or even diesel oil, such as Rotella. I came across this Edelbrock oil for $8.99/qt and was curious if anyone has used it or heard about it. It specifically advertises a high level of zinc for vehicles with flat tappet cams. I know most of you run 15w40 Rotella, but I like to go by the book, so I will be sticking with a 10w40. I've attached a pic of the oil. Thanks!

Rotella 15W-40 would work well.
That other is just 'hype'.
That 'book', was written long before Rotella came out.
Get a Wix filter from NAPA-NO FRAM!

Most all of the diesel oils have changed blends in the last couple years, due to federal emission standards.

You can purchase 4 oz. zddp oil additives from most all cam companies. You can then use any current decent standard or synthetic oil and get flat tappets cams to survive.

Any other oil that you can find that says for off road use only... It a great alternative. It still has the good stuff.

Joe Gibbs or brad penn oil is also an alternative..although pricey.

Do what you feel comfortable with. Most oil problems happen during initial break in..

Thanks for the replies. I'm trying to avoid the need for an oil additive, if possible. I haven't heard of WIX filters, but I am also anti-fram. I appreciate the opinions and certainly welcome more, as I won't be doing the oil change for another week or two.

Edelbrock oil is actually torco oil not really sure what blend though (sr1 or sr5) or possibly a custom for edelbrock? Torco is good oil though. Try napa or any equipment oriented parts house for wix . also our orielys carries wix. 51522 for the AMC 258 i6 / 4.2l and 51060 for a AMC 304

Good to know, Tinman. I also came across this Lucas oil, made for vehicles without cats and contains "high zinc." I found the Wix filter and will give it a shot. Just need to decide between the edelbrock, Lucas, or rotella oil.

Shell Rotella would be a good choice.

B4 the pig pile begins I know he is referring to motorcycle filters but good reading anyway.

Tinman- great article. Also, the Wix filter you referenced, part number 51060 is different than the filter that came up when I typed in my 74 CJ5 AMC 304 . It came back with part number 51258. I compared the two and the only difference is the height. 5.1 vs 4.3 inches tall. Is there any advantage over going with the taller one? If I do, I assume that I will need a little more than the 5 quarts that my FSM states.

Thanks

More filter media and more oil probably wouldn't hurt your 304s feelings

Stopped by my local o'reillys to pick up my oil and wix filter. They didn't have any of the Edelbrock or Lucas in stock, but they could get me some from DC, so I opted for the Lucas, as I have been satisfied with their other products and will be putting their 80-90 gear oil in my differentials. I just received a call that UPS will not ship the oil, so I am back to square one. I think I will trust you guys on this one and use the 15w-40 Rotella in my AMC 304 . I should go with conventional and not synthetic, correct? Will I need to add a ZDDP additive to this?

Also, I'm not sure if my differentials are Limited slip or not. The Lucas 80-90 gear oil says it's safe to use in Limited slip differentials. My question is, will I damage/hurt anything if I use this oil and DO NOT have Limited slip?

I'm going with the GL4 Sta-Lube 85-90 gear oil from Napa for my Transmission and Transfer Case .

Thank you!
