My mechanic who’s getting very, very old...like 75 years old slightly overfilled my 2015 350 AWD. He put approximately 7.3 qts in when it takes 6.6 with filter change. It’s about 1cm over the full mark.

I didn’t notice until I got home and saw that the jugs of oil provided were more depleted that they should be. I feel terrible calling him and asking to drain some, his pride would take a hit and he’s done sooo much extra work over the last 10 years for and not charged me for it I feel bad mentioning some extra oil. If it’s to much I’ll simply siphon some out from the crank case.

By my math i am about 700ml overfilled. On my 2gr-fse engine is this risky? I don’t want damage the engine but also don’t want to over react if it’s not enough to cause harm.

 

That's not good at all. I would come back and tell him nicely or if you don't want to go back to him, try another shop.

 

That's over enough you definitely want to fix. 1cm on that stick idk how much exactly that is be its plenty.
I would fix before driving anywhere, besides to get it fixed if you dont drain yourself. If you do drive it take it real easy. There are a few real good reasons you don't want to drive a car with too much oil so keep the rpms low and prevent from getting to full operating temp if you can (if its close enough to you).

I've known a number of mechanics that to my surprise go by the dip stick when filling oil rather than purely by measuring. Which is a good thing, as long as your not way over or under. Usually the 6.6 ot 6.7 is a guide line, the ones I've known put less and measure, and top off. Run the car, check again, etc.

He just over shot the mark a bit and I'd bet your 10 years of being a client would overrule any feeling of embarrassment. You'd know better of course, but if for whatever reason you dont do it yourself I say go see him and act like it's no big deal

 

Do you know how much they actually put in ur 350 with oil and filter change?

Is a syringe with a hose into the crankcase the only way to siphon it?

 

Last time I did it I wasn't prepared to take off the filter (just a oil filter wrench and cap but didnt realize I had no 3/8" drive socket wrench) so my I did oil and filter a few days apart so oil qty wasn't as straight forward lol. I dont know exactly what my shop has done but now I remember now I should check the dip stick!

I've never siphoned oil. Edit: but I have just looked up people doing that through the dip stick tube.

My only solution would be to drain from drain plug. I've had to do it, its messy putting the plug back in there while its draining, but wipe it down real good after. Possible it would trickle out without completely removing the plug, but that was not my experience on other cars.

 

so I put a small hose down dipstick tube and siphoned a quart out. Going to check the level in a few hours, but I should be good.

Being at the Max line is fine right? I know perfect level is right between the 2 dots but is being at the top mark fine?

 

You want to be at the top mark.

Thsts the first ive heard its ideal to be in the middle mark of the dip stick?

If you have to top off I would use fresh oil not from what you siphoned.

 

I always thought in the middle of the 2 lines was the ideal level, must have read that about another car I owned.

I’m not going to use the siphoned oil.

I also always found it kind of difficult to get an accurate dipstick reading on the IS, so today I also took a Dremel and scored the dipstick to roughen up the metal and give the oil something to stick to. Apparently it’s a common thing to do.

 

Yeah I've had to read that stick 3-4 times. Dremel idea seems good.

So what happened, how much where you over? How far down did it go on the stick when you removed the quart?

 

I took out 500ml, a touch over a half qt and it went from 1 cm above the full line to 1mm or 2 below the full line. I’ve always found the dipstick hard to read, dremel made it slightly easier but still had to wipe and reinsert multiple times.

 

I've been known to do that too

 

thaaaaaats what she said...

 

...glad you caught my humor....Life is so stressful and I find people forget to take a deep breath and joke a little....
