I did an oil change. Thought the car took 4.4 quarts but it only takes 3.7 quarts. I poured in slightly under 4 quarts. The engine is a 1.5 in-line turbo (Honda Civic Si). It’s reading past the fill line slightly. How bad is it? Do I need to pour some out? What am I risking? What symptoms should I be looking for?
This kind of neglect of proper maintenance is why it started burning oil at 100k.
If you want your engine to last, you change the oil every 5000 to 7500 miles.
Lol. Old Honda engines are known for essentially not needing oil. I have a B18 that refuses to die. It’s leaked so much oil before that I got barely a quart and a half out once. I try to top it up every once in a while but with 267k and just about everything else falling on the car, I’m about to stop bothering with oil on it all together so I can justify a new (to me) car.
My old jeep with the 4.0 was like that. I just kept adding oil every week or two when it got down past the safe zone, not doing any oil changes for about 60k. That thing had about 260k on it when the transmission blew up and I didn’t have the time or money to keep going with it. My 2010 is damn near the same at 180k (the pos 3.8), but that motor is due to be swapped soon due to loss of compression.
Being able to take a beating and “not needing oil” are 2 wildly different situations lmao.
Read the manual. Changing the oil too soon is not helpful. modern oils often give the least wear at 8000 miles (the longest chain moleculs break down and that is accounted for by making the longer than needed.
if you really want the engine to last install a bypass filter use 25k mile oil and then do an oil analisys every 10k miles when you replace the filters - only changa oil when the lab says so. the lab will charge more than the cost of an oil change which is why almost nobody does this.
for most of us the engine will out last the gest of the car with just regular oil changes so this above is not useful advice.
We did routine oil changes between 5-6k miles until it started burning oil. I assure you, that was not the issue. We spent a while trying to figure it out before saying fuck it because it never gave us issues.
