“Not experienced in cars might be a dumb question but its been barely a month and my dipstick shows no oil.”source ↗
“I may have placed too much oil, i managed to remove about 1/3 of a gallon out of it. This is what it is reading after that am i safe to drive?”source ↗
“i overdid it a bit because the maximum mark is just below, is it safe or is it just a little bit more and won't cause an issue”source ↗
“I’ve never seen oil that far up and assumed it was a fluke.”source ↗
“Same issue, it’s 4” up from the gauge on the tip. My odb came back with no codes.”source ↗
“Would this be a mistake to buy? What causes do you know of that cause the oil to read that high?”source ↗
“Today I put in another qt and it is above the full dot and I want to know is it fine to leave it like this or should I drain some out?”source ↗
“gotcha, it was sitting already for about an hour when i checked it and this is what i got. would i be able to drive it safety though? i plan on getting a complete oil change tomorrow at valvoline or wtv it’s called but i just needa make sure i can get to work first and then head to the shop lol”source ↗
“i filled it with a big 5qt jug and i put the whole thing in there thinking it was needed since when i checked it before the dipstick was completely dry. then some common sense came to me and thought maybe it was too much. did my research and yeah it was definitely a lot more than needed”source ↗
“Today I added a little too much oil, and after getting off the highway, oil pressure dropped immediately to 18-20 PSI, prompting me to pullover and check, then drain the excess oil and start it back up.”source ↗
“Seems to still idle kinda low, but it was anywhere between 25-30 PSI every stop light on the way home, and seemed like there was some lag on the oil pressure when I accelerated, and it didn't climb quite as fast, but would still hit 60 PSI around the time I shifted to 2nd gear”source ↗
“Anyone with similar problem and if you could share your experience in solving it? 1 liter per 2000km. Service says its normal”source ↗
“I am also suffering from this. 2018 kia soul. Big sad”source ↗
“Ive taken multiple times for that “nothing we can do they all do it its not consuming enough for us to fix it” is the answer i always get.”source ↗
“That used to happen to me all the time, I ended up just buying a longer dipstick.”source ↗
“Hi guys, I’ve just changed the oil myself for the first time and I’m afraid I might have overfilled it, could anyone tell me if I should drain some of it out, or should I leave it as is?”source ↗
“I saw a little bit of white smoke on start up but it think this is just condensation. I don't see any smoke when hard accelerating as well.”source ↗
“Should I do a soak? Where I take out the spark plugs and pour some cleaner down? What do y'all recommend?”source ↗
“Burning oil in a 2003 Jeep Grand Cherokee cut down by half because the oil can unstick piston rings, give better compression, and reduce oil consumption.”source ↗
“The dealerships have been no help and as the car is now out of warranty, want to charge me like crazy to look into the oil consumption its been having.”source ↗
“My mate accidentally put too much oil in his car! Is he f**ked?”source ↗
“Overfilled oil by 2 litres and drove for 30 mins. Fucked?”source ↗
“Got my car back from the mechanic yesterday and noticed it was a little high.”source ↗
“Let it sit overnight to make sure it settled & it still looked a good bit over the max when I checked in the morning.”source ↗
“Upon getting the oil change, the place discovered that there were 8 and a half quarts in my 2017 toyota corolla, which is almost double what it should have been.”source ↗
“I feel so dumb for not catching it before.”source ↗
“I would be more concerned on why it's over full. It was either over filled at the last oil change or it could have a leak letting other fluids like gas or coolant in and causing it to be overfull”source ↗
“2011 rav4 4 cyl. Is this ok or should I worry about draining some of it?”source ↗
