Default Better method of checking oil?

There has to be another way to check the oil level rather than the dipstick. I believe that it is inaccurate. I park my car in my garage every night and check the oil every morning and you would think it would be the same, but no. Sometimes it reads over what it did the day before and some days it reads under. Recently after driving for a hour or two i came home and checked it and it was a little under the F (this was while the motor was warm). After letting it sit overnight I checked it again in the morning and it was a little over the F and under the notch. what???

I recently did an oil change on an audi and there was no dipstick but there was an electronic oil gauge that reads when the car is warm and turned off. would it be possible to install something like that ?

If the engine was recently running, let it sit OFF for 5 or more minutes to allow all the oil to drain back into the pan.

Yes, warm oil will show a bit higher than really cold oil, but the draining is more important.

Using an electronic gauge is for 2 basic reasons.
-people don't check oil, so the OEM designs for careless people.
-some engines have so many covers under the hood, it's a PITA to get to the dipstick.

So no, there is really no better way. Try to check in a common parking spot that is close to level and after the engine has been off a bit.

you can remove the o-ring on the dip stick. it gets rid of the suction of a tight seal. then slip it back on after checking. there is a company selling dipsticks with a pressure release just like removing the o-ring for like 70 bucks.

His issue is not pulling the dipstick, it's the inconsistent readings.

The method used in motors for over 80 years isn't good enough?

Between the low and the full mark when oil is cold, is the Operating Zone. OCD much, oh wait I do that too. Dukes

In consistent readings are caused by the oring.

i've had no issues with these:
1. stop checking every day
2. take 3 readings
3. check when engine is cold and been sitting for at least an hour

and yes the ej25 is kind of a pain to check the oil on

Over/under a few mm's wont hurt a thing. Edging toward the low is what youre looking for mostly.
Your engine has some range when it comes to the amount of oil in the system. Youre looking for massive fluctuations, not inconsequential differences.

I check it every two fill ups. And i try to pay attention when backing out of parking spaces to make sure im not dumping oil somewhere.

You can sweat the small stuff, i get it, but this really isnt something to get your panties in a bunch over.

FYI - I also have an Audi - and guess what the most recommended 1st purchase is? YUP - Oil Dipstick!!

Why - because the Electronic tracking is somewhat unreliable and makes checking the oil level complicated....

So go with the dipstick - Oil should be checked about 5 minutes or so after driving - flat level ground - and I typically check it 3x over to confirm findings.

Isn't it a time honored Subaru tradition to be checking your oil at every fill up? As others have said, if it's at or below the low level, add oil. Otherwise, you're good to go.

Buy a new BMW.

No dipstick and you rely on a computer to estimate how much oil remains in the oil-pan.

Then at the OCI, you drain the oil and fill it back up per the manual and that's it.

Doesnt work. The oil fill tube sits ontop of the rocker cover to the driver side head. The suction created by the oring is strongest at the tube inlet near the oil fill line in the pan.

Easy to experiment yourself. Open the fill tube, check oil. Then remove oring and check oil, it will change.

exactly. i wasnt gonna argue anymore over this. the oil cap has nothing to do with the dipstick tube pressure.

Be cool if it was like a motorcycle with the little window showing you where your oil is at

So you crawl under the car to see the window? Or lay in the snow, on wet ground?

That sounds infinitely easier than using a dipstick.

ive been kinda mowing over this issue.. As my oil disapears on a daily, Ive become best friends with my dipstick.. and Ive realized I dont know a whole lot about it. I mean I get it but I feel like I should know more...

I actually read the cars manual and it says nothing about reading your oil while its cold.. It says you can add oil while its cold but to keep it under the F line...
Which leads me to my question of when you get a cold reading, besides it alerting that you have no oil, what eaxctly is that reading telling you?

I get to operating temps, stop and wait some minutes and check and ill be close to F, let it sit hours and it drops back down to halfish where it starts at cold

Most fluids expand when heated, so when it's 20*F out and the car has been sitting for hours, the oil will read lower than a few minutes after shutting the engine off.

Think about the oil temp, then compare to where it is between the dots. You don't want to be low when the oil is warm/hot, you don't likely want it near the top when really cold.

The upper notch is the max hot spot.
