Burning oil after changing to Blend

Status
Not open for further replies.
I would go with a conventional and perhaps take it a bit easier on that tired motor.

As for the consumption, we can not specifically blame it on running the oil low but if you run your crankcase 40% below it's capacity then the combination of age and oil may have done something.

It might take a while for new oil to settle in.
 
As noted earlier, check your PCV. Also the max life may have cleaned some of the goo that was sealing the rings or gaskets.

2QTS is pretty high for an OCI?

Any drips on the ground? Valve cover gasket? Is the oil still dark black or milkshake looking. Could be an internal gasket leak.

I would do as suggested above and find out what your dealer was using before and get that. Conventional most likely if they put a 3000-5000 mile oil change sticker on your car.

Have you taken the valve covers off and see how much varnish and sluge is in the top of the engine. 200K miles of conventional will have quite a bit of varnish. Cleaning that off may have exposed an existing leak or caused a new one.

I happen to own a car which suffered from neglect by the previous owner/s

Switching from one brand to another, and between conventional 15w40 and 10w40 syn-blends hardly seems to have any effect on oil consumption, although i have not tried Maxlife.

I've used Maxlife in various vehicles and never had consumption problems. Actually, yeah, my 08 Escape with 220K on the original 3.0 V6 that my coworkers daughter drives now eats a bunch of oil - we tried a few different high mileage oils, Maxlife, O'Reilly High Mileage, Castrol GTX HM, nothing helped - so it's not the Maxlife's fault LOL. But actually it will burn ANY oil, whether conventional, blend, synthetic, high mielage, 5w-20, 5w-30, 10w-30, no matter what you put in it's about a quart every 1K miles, even with a new PCV valve.

Might be time to go a little thicker-I know it's a different engine, but oil consumption in the 230K mile '98 XJ 4.0 in my sig with MaxLife 10W40 is a FRACTION of what it used with 5W30.
 
I started off buying the Mopar 5qt jugs from the dealer, then they suggested they just refill them with their bulk, for cheaper. So I did. I guess I can't guarantee that they filled it with 5w20, but I did specifically ask what oil they run in that engine, they looked it up and verified 5w20.

I was under the impression that you can't just up and decide to go thicker on newer technology motors due to much tighter and specific tolerances.
 
Maybe I just didn't see it but what is your oil change interval? If dealer was changing it at 5k and you are going olm then it was using before. This is not considered abnormal. We need more information just as how far before it loses a quart. Lots of miles and some consumption is normal. Yes if oil is run low it will consume more as oil is being depleted.

That was my first thought also....what grade ARE you using HemiMoparGuy1981?



This could be a possibility.....

But wow, 1 quart in 750 miles is OK after only 50,000 miles? Makes me want to RUN from FCA.

(Oh, and they misspelled "than". Quality control what's that?)
 
I concur: changing oil formulations has something to do with it. And high mileage engines, no matter what the make, will at some point finally start to use oil. Maybe we're witnessing a double witching hour....
 
Wifes Acura has 210K miles on it, had never drank a drop of oil.

Last oil change I used synthetic Maxlife and it has consumed 2 quarts in 6500 miles.

I'll try a different oil next time and see what happens. The car since new has gotten the cheapest, on sale/clearance/rebate, synthetic 5W30 oil I can find.
 
Not trying to be a wise guy here, but I agree with the posters in this thread who feel that running a high mileage vehicle 2 or 3 quarts low on oil for any extended period MUST increase the wear rate on the engine. Then on top of that leaving 4-5 quarts of old oil in the crankcase and just topping off isn't doing your engine any favor.

That right there is enough reason not to purchase a Chrysler product.

This often happens when oil has "sheared" and is now "DONE".

Yes, exactly.

It is ALSO how they can offer those really long warranties.
 
I've had that happen to me periodically. Same car. Just recently did an oil change at the dealer, used bulk 5w20 semi-syn with previous fill a Penn Synthetic mileage at 120k. After about 150 miles of driving I checked the level and it had dropped mid-point between the full and low range on the dip. The dip registered full when I picked it up. Also, used to run 5w20 dino and I would have to top off periodically after about 2-3k but when I switched to Penn Synthetic I typically didn't have to top off except when it got into the 6k+ range on that oil. I just ran a couple of hundred miles of this holiday weekend and the dip showed it was still at the full line.
 
Might have been due to Valvoline changing to new D1G2 formula. Sometimes, a switch in additive pkg within brands or switching brands all together can cause consumption to go up for 2-3 oil changes. Should settle back down after a little while. Just check level more often.

750 miles to use a quart of oil for high mileage is just a spec just like GM as well as many more manufacturers spec 1qt every 1k on new vehicles. I had a GM that used a qt every 1k since it had 30k on it and they said normal. Since I just bought it not much other than blow it up to get new engine. By the time it was finished it still used same amount but had over 300k on it. Company bought oil luckyly since at that time I was driving between 60 and 80k a year.

Maybe the dealership oil was conventional, regular Valvoline, so try that. If not that, then try some other brand of conventional oil. I think the closer it is to full synthetic, the more likely you'll get consumption. Given the Maxlife consumption, I'd avoid High Mileage oils too.

This is my answer to. Maybe try Pennzoil Conv. 10w30.
