when using the M1-301 filter and Mobil1 oil, my 4.0L tick got MUCH MUCH worse. After switching back to the stock size filter and the cheapest dino oil I can find, the tick became much less apparent at startup.

I run a Motorcraft FL-1A or Purolator PL30001 oil filter with Valvoline or Rotella-T 10w30 now, with 1/2 qt of ZDDP additive, and it still ticks but only sometimes for a few seconds at startup.

Oil isnt going to change it, you need to look into the rocker arms and valves in the top end of the motor.making unnecessary valvetrain noise

What does the ZDDP actually do? Does it reduce engine wear? What brand do you use? If I use Mobil 1 10-30 synthetic, can you still add ZDDP? Thanks!

I've heard for noisy engine on startup, use a 5w-30 dino or 0w-30 syn. Along with some Marvels Mystery Oil.

I've also heard of people adding ATF fluid to their oil for the detergent but I wouldn't know how much to use or for how long.

I'm going to try the 5w-30 and Marvels at my next oil change and each one thereafter for a while. Being that I only drive like 2-3000 miles a year, it could take a while.

Here's what ZDDP is:
Zinc dithiophosphate - Wikipedia, the free encyclopedia

Theres a ton of ZDDP/engine break-in additives....Lucas, ZDDPlus, Cam-Shield, Red Line, etc. I use Lucas cause it's available locally.

Thanks for the link on the ZDDP and the Lucas! Does the TJ have flat tappet lifters? Any opinions on this QS Defy oil?

Motor Oil, Transmission Fluids & Synthetic Oil | Quaker State

I wonder if this would be an improvement over the Mobil 1 10-30 synthetic? I probably costs less. I've been using Mobil 1 10-30 synthetic and Mobil 1 filters since I bought the Jeep with 13.5k miles. The PO used Amsoil. I now have 62k miles on my O4 Sport. I've noticed a clacking sound occasionally on startup, but it goes away once I start driving. I wonder if this is causing any wear? Thanks again!

I was thinking of adding some Marvels Mystery oil... But since I just did an oil change I have the max in there... Am I able to remove the oil filter without losing a lot of oil (more than a qt.)? I do need to remove some to add the marvels so I figured remove and replace the oil filter and there should have been enough lost in the filter I would remove to accommodate the amount I want to add... thoughts ?

the thing about diesel oil is that it has alot of sulfur in it as a detergent in those dirty ass diesels! also the diesel engines are vastly different and are built to withstand the extra sulfur. in a gas engine, the sulfur will burn and i mean burn the rings and valves out of your engine. get it out, flush with cheap oil for about 3-4 days, and replace with royal purple or some other oil of your choice.

I went from regular 10w-30 to High Mileage and it seems like the tick in my motor got worse too.

Mobil 1 Turbo Diesel Truck is specifically rated for gasoline engines too.

Assuming you are refering to the OPDA tick, my tick got a tad more noticeable immediately after I switched to the Turbo Truck, to the point that I could hear it while sitting in the cab at idle. However, within 10-20 miles, the ticking had died away completely. To be safe I still have a new OPDA in the garage that is in the process of getting Fogmodded. As soon as my Aeroshell arrives, I'll be able to install the new one in the engine.

I didn't read all the thread as I felt it was starting to get into an opinion thing...SO here is another based on my experience.

My '04 has the tick. Started about 100K ago. Now has 150K. It SLOWLY got more noticeable. I mentioned it to my Father around 80K (he is a retired Diesel/ and Air craft/ airplane mechanic.

He suggested fixing the motor wouldn't take that long and not be that hard. I am lazy, and don't have near his skill. I asked for other suggestions. He said slightly heavier oil.

I went to MOBIL 10w30 full synthetic and also use a bottle of "Lucas oil treatment for synthetic". I use a WIX filter. I now change oil every 5K. There is no more TICK that I or my father can hear. Oil usage is less than a 1/2 quart between changes.

Good Luck!!

I am currently doing the oil cup mod on my new opda and hopefully will be puting it on next week .. So I am hoping hat will help .. But until I do the tick got louder with the oil change.. And driving me nuts. Oh and I only have 45000 miles on my 06 so I am worried about the slight tick at that low mileage ..

Like train said above .. It is rated for gas engines too and many recommend it.. So I would hope it does not burn the parts up as u say.. What are your thoughts on the oil being rated for both ?

Mobile 1 made my tick/knock worse on my TJ.
Fooled around with a few different brands.
All did ok.... Thinner helped the oil reach the top quicker, she was pretty quiet when at operating temperature.

there are some diesel oils that are not for gasoline engines yes, but M1 TDT and rotella are not "diesel" oils. they are "Heavy Duty Engine Oils" (HDEOs) and are rated for all sorts of stuff. they are great for gasoline engines as well as diesel and many people use them in motorcycles too since rotella t3 and t6 are wet clutch compatible. they are basically your do all oils made to be used as a bulk fleet oil. don't confuse HDEOs with diesel only oils.

as far as ZDDP goes yes its a great anti-wear additive, yes our jeeps have flat tappet cams but the spring pressures out 4.0 engines have are not very high and many have proven that its not required to have more ZDDP then whats in your everyday car oil. Using a ZDDP rich oil is popular since its better to be safe then sorry and the only down side to using ZDDP is possible catalytic converter damage in long term conditions.
I use oils containing extra ZDDP like HDEOs or quaker state "Defy". they are not mandatory but a good idea IMO since they don't cost any more then other oils.
I will never use a ZDDP additive though since every oil is specially blended to work and adding stuff to it might upset the balance the large companies spent time formulating. esp since half the additives you guys are talking about don't have any zddp. MMO has no zddp. Lucas oil stabilizer IMO is junk and also has no ZDDP IIRC.
just use any oil you like but if you want to play it safe use an oil thats already ZDDP rich. theres tons of them out there. any HDEO, most high mileage oils, quaker state Defy, M1 0w-40 ect...

Good info. I like technical answers like this. Thanks.

And to clarify my ticking issue, my tick did get louder after the switch to Mobil TDT, but after 10-20 miles of use went away and hasn't returned. This is still with the original unmodified OPDA.

Thank you for the information! I'm have six quarts of Mobil 1 synthetic left and after that, I'm going to give the QS Defy a try. I've been using the Mobil 1 filters as well but might try Wix or Napa Gold. i'll have about 67k by then. Thanks again!

I ran 2 runs of Mobil 1 TDT in my jeep last year going from summer to early winter. I had no ticking issues and the jeep probably ran better then it ever has and sounded just as good.
but I did have a peak at the specs a while ago and the 5w-40 is almost thicker then a normal car 10w-40 and especially thicker then a 10w-30 when at start up (40 degrees Celsius) so you jeep might not like the thicker oil. i used the oil mainly during summer and fall. for whatever reason its pretty thick at start up considering its supposed to be a 5w. maybe just try something different. try out rotella t5 10w-30, mobil 1 0w-40, QS Defy 5w30 10w30, and see if the tick is the same.

if your tick doesn't come back then i would just run it.
