So my dealer put 5W20 instead of 5W30 in my 2010 4.0L Ranger.
Should I worry about it ?

 

no i wouldnt worry about it...how do you know they put 5-20 in it

 

Did your manual tell you that you needed 5W30?

I don't think there is a big difference though. But I may be way off

 

Did they tell you why?

 

I dont know what "mtl" is for location. But 5W20 is oil for people who live in colder climates. So I live in Alaska, I'm just today doing a 5W20 oil change.

 

unless your pulling 6k all day then no dont trip, but if you feel like your abusive then definitely swap it up to 30w

 

even if you were extremely hard on it that slight oil change wont matter. its fine leave it. Ford switched to this weight for almost all engines.

 

I live in Canada.
Its written on my invoice.
No i don't pull nothing and i'm not that abusive so i'm gonna leave it and at my next oil change next spring i'm going to put 5W30.

Thanks

 

it was my understanding that most fords switched to 5w20, i would check your owners manual

shouldn't make any real difference on a newer engine

 

Bro, once again, us northerners use 5W20 because it's better for our trucks in cold climate.

 

Maybe I should be using 5W20? My oil cap says 5W30 so that's what I've always put in...

 

montreal

 

I put 10-40w in my 96 3L. Doesnt hurt nothing. I actually feel it better protects it. may lower my milage but w/33's, 3.73's and a 3slow theres not much to do about it. lol.

 

there was a technical serivce bulitin that came out awhile ago about most fords, including the rangers now have a 5w-20 recomendation. it was on my desk till about 2 weeks ago when i pitched it. im sticking with the 5w-30 though. with over 100k why change now?

 

Ford did back-spec a lot of engines to 5w-20, but the SOHC 4.0 was not one of them. That oil is too thin for that motor, I'd switch it out immediately! I'd also go back to the same dealer and have them fix, and document, it. I'd also ask them to provide some documentation that 5w-20 is acceptable for that application.

 

one oil change aint gonna hurt

 

i work at an oil change place, and we do that sometimes when were out of a certian weight oil, it doesnt hurt anything on your motor, my truck calls for 5w20 and ive put 5w30 everytime cuz thay dont make the oil i use in 5w20

 

Going up a weight is fine, although your fuel economy may decrease slightly. But going down a weight is risky to the engine, the oil may not be robust enough to adequately protect the engine. There is a reason that engine was not back-spec'd, and I'd bet that the Ford engineers know more about the lubrication requirements of that engine than the oil change kid at the dealership. Why not be safe, and return it to the dealership and have them correct their mistake?

 

i had 5-20 put in my truck about 5000 ago and it had no ill effects...and im willing to bet the dealer wont do anything

 

No ill effects that you are aware of. I'd love to see a UOA of a 5w-20 run for 5k in that engine. Dealer won't do anything about what?

 

they wont admit they put the wrong oil in...and i always change my oil every 3000...wont go any longer...id rather have 5-20 than 0-20...pours like water lol

 

I change it up, I go from 20/50 down to 10/40, just to be different

just kidding, my last oil change they used 5/30w, but seeing as Im in SFL and our coldest days are about the same as Canada's summer nights... oh, and my engine is the 3.0L so may have a little mroe wiggle room.

 

I'm getting worried here...I mean I called at my dealership and the technical advisor told me that its nothing to worry about.

 

you have nothing to worry about PW01 is overreacting big time...just make sure you put 5-30 in next oil change...you dont beat your truck or tow a lot so you will be fine...hes just overreacting

 

You keep on saying it's the wrong oil when both ford and people in northern climates agree that 5w20 is best. Pw01 isn't saying anything worth listening to
