Oil Additive?

Hey All,

Anyone use Lucas or any other additives in their JK? If so what do you use, and how do you like it?

I am getting ready for my 5K oil change this weekend. Changed it at 1K with Royal Purple 5w20, and planning the same again now at 5K and every 5K after this. I love the royal purple and it's the only thing I used in my Hemi, but cold starts could be a bit better. That first 2 or 3 seconds after a cold start you can really hear all the parts until the pump gets going. I was thinking of throwing a bottle of Lucas into the mix to see if it would help with the cold starts? Some people rave about the Lucas additives, but I have never used them before and I am a little unsure. Would love to hear some thoughts on the subject.

Thanks,
Jeff

A-Lucas is supposed to thicken your oil, and it flows like molasses at low temperatures. Not sure why you think that'll help with a cold start.

B-it's basically heavy-weight oil with no additives.

Here are some results from a chemical analysis of an unused sample:

TBN - 0.1 (Total Base Number: basically remaining active additives)
Visc - 615.3 (This viscosity is roughly 10x what you want)
FP - 435 (flashpoint, this is fine)
Calcium - 3
Magnesium - 1
Phosphorus - 4
Zinc - 2

The stuff is basically 80w oil with no useful additives. It's going to hurt rather than help.

No additives, not necessary in new engines. Run quality fuel and that will help with carbon build up and run high quality full synthetic oil. If you have noise during a cold start then use a different oil, in my cars I have run nothing but AMSOIL synthetic for years and even at -40 no upper engine tick after start up

My 07 3.8L uses oil....I have reduced the amount by going to 10-30 . ( no, not another oil thread !!) Reading a lot of the dreaded oil threads here , Oil additives do not have much support here. People have no trouble using 5W-20 oil but hate additives!
I bought a bottle of the Lucas Oil Additive. I have not added it yet. My next oil change is around Veterans day. Cooler weather then, so I may wait til next spring to add it. I hate to run Viscosity builders in the Winter. Too much chance of spinning a bearing in these 3.8L engines.
I do use other Lucas products, and they are top Quality. I also use Power punch products as they are local to the NW area....

Out of curiosity, how much oil are you burning to make it worth buying extra stuff to pour in?

Cool beans, thanks all! Seems to be some what of a consensus between here and Facebook. Skip the additives and think about a different oil.

Thanks Again,
Jeff

Jeff,
the noise that you are hearing on cold start up, is very normal for some of the VVT 3.6 engines. Some just do it more than others. If you are concerned about it, then I would have it checked out by your Dealer.

My 2013, does not make the noise at cold start up. But I road tested some, prior to purchasing mine, that did.

I have yet, to find anybody that can explain, why some do it, and others don't!

Started out using a bunch.....like a quart every 1000 miles, some times more...After foolin around with trying different oils, and different weights...I'm now down to about 1/2 to 1 quart between changes. I only change oil once a year ( Veteran's Day ) , I don't drive the Jeep except for just playing around, getting out of the house once in a while.....It just sits in the shop. So yearly oil changes are only 3000 miles or last time it was barely 2500miles..
I have found that Short trips in traffic will kill the oil consumption ( meaning It uses more oil ) . I'm somewhat happy with it now, at least I know what to expect when I'm on the road. I don't feel like I gotta check the oil every time I stop to Pee....
We recently returned from some old Gold mines in Eastern Oregon and that was a 1000 mile trip , and planned to go to some Ghost towns in Calif.
I bought the Lucas Oil additive because we were going to drive the Jeep down to Californication to some Ghost towns this month. It being Hot out I was going to change oil and add a little to see if it helped with the Oil Consumption on the highway in the Heat...Plans changed...
So far in my oil "experiments", I have not tried any additives yet.
Besides, I use it for other things in the shop, works good to use as Lube for sizing rifle brass, putting together stuff and lubing bearings, I use it for all kinds of stuff and I was out of Power Punch so I thought I'd give Lucas a try.
I use their 2 stroke additive in my powersaw, works good there.... "BH"

I've heard some of their products are good, but I don't really know. But I've done a fair amount of reading on the oil stabilizer. It's basically 70w or 80w oil with no detergents. So you're diluting all that stuff while thickening your oil. In Florida or Arizona that might not be a big deal, but I wouldn't even consider it anywhere with a real winter. A quart of oil a year is a lot cheaper than a spun bearing after a cold start.
