High Oil useage

Postby jhonjhon » Sun Jul 14, 2019 6:59 pm

Hello, I'm a new owner of a 2011 fx50s, 94000 miles, and completely love the car. Indo have a problem that any opinion would be appreciated. About a week after i got it the engine sounded funny and i found it 3 qts low on oil. I topped it off with mobil 1 5w30. About 3 weeks later it is another qt low. Possiby 500 miles in the 3 weeks. There was a jiffy lube sticker with a return milage that wasn't due for another 1000 miles. I assume the nissan dealer never even pulled the dip stick to check the oil, washed it and put it on the lot. Tomorrow i plan on a fresh oil change and filter and keep close watch on the level. I don't see any leaks or smoke but the exhaust tips seem very black to me. Any opinions on what i should be looking for. I'm hoping the crap jiffy lube change is causing all the problems. I was going to use mobil 1 high milage. Are there any better options and would an oil additive suchnas lucas be helpful. Thank you again, john

That dealer may have sold a lemon , and Lucas , that dealer probably put 1 quart Dino oil to 4 quarts LUCAS !
Jiffy sticker - from any previous owner - means nuthi 'n . :crazy:
All due respect , I'm hopin if that's what's really happenin you can take it back , Man , :yesnod
My opinion LUCAS = Junk for a JUNK CAR :lolling:

I don't think the dealer did anything to it. I was only wondering if any additive would slow down the consumption. Taking it back is not an option. Thanks

Sorry to hear that , because seeing full quarts+ low , and SO quickly ,the poor engine seems like money pit,would be to fix. No-one would want to give you a lot of things to "fish" around , wasting time if you could remedy this as a bad sale. I feel for you ,man. :cool:
Hearing the details also seems your way beyond any LUCAS fix , in my day we had S T P (aka Suck The Public) .

Thanks, just got an oil change and filter, dumped a jug of techron in the tank. Maybe it's me, bit it seems smoother and doesn't buck as I pull out. Mechanic wiped the inside of the exhaust tips and it was sooty. He said it was burning. I'm just going to see how it goes and how long it takes until I have to add again. Thanks for the reply

I also found top tier gas for it and filled it up. Im hoping for any improvement. At least now I have a baseline to gauge how bad it is

Hello, and I hope your experience with your recent purchase has gotten better by now. Any updates to share on the oil issue?

I was also curious; although most people don't buy an FX50 solely for its fuel economy, might you have been monitoring your gas mileage during the same time period?

After the oil change it has gotten much better. I guess about a at per 1500 mi. I know it's still alot but I'm hoping it's going to continue to improve after the next couple oil changes with the proper oil. Gas mileage is about 17.5with 60/40 highway town miles. Thanks

It's good to hear that things are trending in the right direction.

I would keep at it, trying to address what seems to be deferred maintenance especially on the fluids. Consider addressing your transmission fluid, rear and front differentials, brakes, as well as the coolant system.
For the engine, my preference would be any good synthetic oil and quality oil filter - change it frequently for the time being. Yes, it is expensive, but here we are trying to invest a little money to avoid spending a lot more on engine work. I also avoid high mileage oils and Mobil 1 (personal preference).

Generally speaking, the VK50VE engine does not seem to get bad reviews with regards to oil consumption so I hope this is a temporary issue for you.
