3.6l Oil change issues

[Grad12]

My truck has 12 000 kms on it and this is the second time I change my oil with the same issue. The manual indicates the truck takes 6quarts or 5.7l of oil. I fill to that exact specification but the dipstick isn't even touching oil! I tried starting it up and letting it run for -30 seconds. Finally when the truck sits after two hours the dipsticks just barely touches oil. I purposely filled my truck with another half quart just so the oil touches the dipstick halfway.

Does anyone else have this issue when changing the oil? I know for the 2014's it's a new oil filter, so I don't know if that's the issue.

I contacted the dealership and they gave me the: "we've done 100 000 oil changes so I think we know what we're doing." "You need to put in 5.7 litres."

If they are only putting 5.7 litres of oil in the new 3.6l's they're not putting enough in, or my dipstick is way off.

stupid question...are you taking the truck off the ramps before you check the oil?

 

[Grad12]

I don't use the ramps, I just crawl underneath. It's on level ground. Good question though. Twice I've done the change, both times on different ground.

Oem capacitys are approximate. Oil temp and draintime can greatly affect how much oil you put back in. At the dealer they dont even let the oil drain for 5 mins before the plug goes back on. If you let it drain an hour or during lunch or whatever alot more oil is going to drip out. Depending on the situation i ofter put in at least a half quart more than the spec. Let the dipstick guide you, it never lies.

^^ what he said. I always get an extra quart, I never pay attention until the last 2 quarts then start checking the dip stick religiously.

And I have been a victim of checking it with it still on the ramps, im like "WHAT IS GOING ON, AHHHHHH!!!!" hahaha

However to answer your question directly, I put the recommended in and it shows on the dip stick, I have a 5.7 tho, but again, the dip stick is your guide..

When I did my 5.7, I knew the stated capacity was 7 qt. I had a 10qt drain pan and it was easily close enough to 3/4 full that I knew the majority had come out. Hell it shot out of the pan like a fire hose. Then I put in 6.5 qt, checked the dipstick and it read normal, started the truck, revved a couple times after 10 sec, checked again and it needed the 7th quart.

 

[Grad12]

Thanks for the info guys. I'll keep doing the oil change and checking the dipstick like I do. I do let the oil drip out for about 20-30 minutes, so that might account for the extra half-full quart.

I have the same issue for whatever reason. My Hemi takes 8 quarts and everyone else's seams to take 7. So far I haven't had any leaking, so I believe it actually needs 8 quarts. Make no sense but whatever.

My Hemi and the 05 I had before both take a perfect 7 with filter. I don't know where that other oil is going but a dipstick is not exact science for sure. If I do extended drain I have to add some so maybe if I started with 8 I would not have to

Reviving this thread as I too need to use 7 quarts in my 3.6L for the dipstick to read full.

I have a thought, but I don't think it would be enough to make much difference in dipstick reading.

So for the question, could Bilstein 5100s at 2.1 make the dipstick read a full quart low?

I have changed mine twice with stock suspension. Took 6 qts. Its better to be a little low than too high if given only those two options.

Still want to know what others think though about leveling...

Just for giggles you could compare the length of your dipstick with another 3.6. I had a 57 Plymouth that had the wrong dipstick that was way off.

I may actually go to the dealership and do that.

Or if someone reading this could measure their's...

2012 5.7 Hemi here. With a Royal Purple 20-820 oil filter, mine takes about 7.5 quarts.
