OMG, don't start that!

 

I had bad lifter chatter in my 4 cyl ranger upon cold startup. I used Lucas oil stabilizer and it didn't make a sound after that. I know I'm gonna catch some heat for posting this cause a few people say its snake oil but I've had good results with that product. You should try it but make sure you post your results.

 

Google it. Be your own judge. I won't use them. There is days of information on the topic out there, no need for us DFers to add any of our knowledge to the mix.



To answer the OP's question before this thread turns into another worthless pile of DF rubbish;

5POINT9, if you live in a colder climate, I wouldn't recommend 15w-XX oil. Nearing fall, the oil you put in now will still probably be in the engine when snow falls. It probably won't hurt the engine any, but your lifters may actually get louder the colder it gets. Fortunately, diesel rated oils have a solid additive package including quite a few detergents in them which would help clean the lifter orifices. But I wouldn't wait until fall to try it out.

Without any additional information or engine service history, I would recommend a simple engine flush. Buy a bottle off the shelf and follow the instructions on the back. I'll typically drain the old oil, fill it with the cheapest new oil i can find, add the bottle of engine flush, do the flush, and it'll always drain nice and dirty after the flush.

If the engine is old and worn out, and it were my truck, I'd throw some 15w-XX oil in there, and substitute a quart of it for Marvel Mystery Oil to see if it gets better. Then I'd drain it out before the ambient temperatures got too cold. Haven't tried this, but sounds promising.

My $.02.

 

You left this out in your post.

 

Don't put any kind of additive in your oil. That stuff does nothing but destroy the chemical properties of the oil and removes the oil's detergents. If you are having lifter clack at start up I'd go with a thicker oil if the winters where you live aren't too harsh. If you live in the north where winter is really cold go with the thinner oil.

 

Wow I had no idea! What filters do you guys use? I just put on a purlator pure 1 are they any good?

 

Anything other than Fram. I usually use K&N but the consensus around here is WIX I believe. Read this from the DIY section.

That's what I'd do, but always run the quart of MMO. Lifters are little trash cans that catch anything/everything that's circulating in the oil, and on a high mileage engine the additional detergent will keep more of the ash and miscellaneous other crap in suspension so the oil filter (rather than the lifters) can catch it.

 

If the lifters catch crap in the oil, then what purpose does the filter serve?

 

Are you using dino or synthetic oil ?
