I have 8000 miles on my 4dr si and I have had to add a quart and a half of oil in the last 3000 miles. its not leaking anywhere that I can see on a lift, so it must be burning it. my 1st oil change was @ 4500 miles @5%. has anyone had this problem?

 

How did you break it in? Be honest...

SMo'

 

Whoa I just noticed you said 4,500 miles at 5% life? You were driving the **** out of it! I am at 4,000 miles right now with 50% life!

I think you damaged your car, if so, nice work, RTFM...

Your Signature kinda' gives you away as well...

lol

 

If he broke it in hard, how would that affect ring seal? Take your head out of your ***.


If your drinving the car hard, it's gonna burn oil new engine or not and 1 1/2 quarts in 3k miles isn't alot.

K series motors burn oil in the higher RPMs. There is nothing wrong with your motor, just make sure you keep an eye on the oil level every fill up or so and top off when necessary.

 

Hitting the oil life at 4500 miles is beating on the car beyond what it wants, especially with the factory oil...

ANY engine burns oil at high RPM's not just K series engines...

Driving the car hard and burning 1 1/2 quarts of oil is a lot! Especially a new car... I had a boosted straight 6 supra that was 14 years old (never rebuilt) and it did not go through 1 1/2 quarts in that amount of time, and that was boosting hard at all times in the summer (90 - 105ºF outside)... Supras do not run cool either, they run hot...

I have 3,000 miles on my 07 si and I had to add 1 quart of oil. My oil life is at 40%

I shift at the recomended shift points detailed in the manual. I've hit vtec maybe 4 times.

Wow I didn't know that. I don't understand the faith that some of you seem to be putting in the oil life indicator.
If you reset it without changing the oil it doesn't go down to were it was before. So it doesn't measure anything that has to do with the oil. It only seems to go down with miles. Heck some peoples don't even go down with miles.
Hell I don't even look at the damn thing. I check my oil when I fill up, wash the car, and I change my oil at 2500 miles. for Honda oil life indicator.

CR/ rod ratio/ red line all play a role in how much oil an engine consumes. Your supra had all those in its favor. Hondas high hp engines have always been know to use oil.(search the type r forum) Most toyotas are simply better engines

Actually the oil life indicator does not go off miles, it goes off RPM's, speed, and temperature... The corporate website has a really cool video about it...

I cant post a link since you need an account to view it, but feel free to create one for yourself...

How would compression ratio and "rod ratio" have anything to do with how much oil the car uses? Do you mean the stroke when you say "rod ratio"?

My supra had all those in its favor, how so? Especially with an additional two cylinders... The supras redline was 6,500...

7MGTE: Bore: 3.27 Stroke: 3.58
2007 Civic Si engine: Bore: 3.385 Stroke: 3.385

rod ratio = rod length/ stroke a motor with a low rod rato side loads on the piston wall affecting the ring seal

motors with high CR have higher cylinder pressure at every load and rpm. Your supra may have higher peak cylinder pressure but only when in boost.

 

7MGTE: 8.4:1
Si: 11:1

What the compression ratio is under boost I couldnt tell ya' but you did mention the Honda "high horsepower" engines... The supra was pushing 250lbs of torque and 232 HP, that was back in 1989...

I dont see how a short rod would cause more pressure on the wall then a long rod (since the long rod will have more leverage, this is not considering the precision of the engine mechanics and age since 1989 to current)... But the longer stroke I could see the potential for burning more oil since the piston travels further... Both of which dont support your theory...

This all depends on the size of the crank as well...

SMo'

 

in 5000 miles on my last oil change I was only at 50% didnt add a drop

 

7MGTE ROD: 5.984
STROKE: 3.385
ROD RATIO - 1.7677

I cant find the specs for the Si... Maybe you can...

it shouldnt matter at all how it was broken in..
since the motor was broken in long before in was even in a car.

these motors arent just built and put in cars with hopes that it will run.
theyre all run on dynos before coming anywhere near a car, to make sure everything is in proper working order.

I understand that, but you must still take care of the engine when you first get it... The engine comes with special oil for a reason, the corporate website states to drive it easy, vary RPM's and not full throttle the vehicle for at least the first 600 miles... Now why would they say a thing like that?

SMo'

 

From the website:

"What is the break-in period of my Honda?

Help assure your vehicle's future reliability and performance by paying extra attention to how you drive during the first 600 miles (1,000 kilometers). During this period:

Avoid full-throttle starts and rapid acceleration.
Avoid hard braking. New brakes need to be broken in by moderate use for the first 200 miles (300 km)."

"Why should I wait to change the oil the first time?

Your Honda engine was delivered with an oil that is specially formulated for new engines that have not yet developed their "natural" wear patterns and may contain minute particles from the manufacturing process.


American Honda strongly recommends this special oil be left in the engine long enough for these wear patterns to develop, usually until the first maintenance interval specified in your Owner's Manual, based on your specific driving conditions."

thanks to the few that was positive. I was just checking to see if anyone else was burning oil. we all have our own way of braking things in. I have found with all the motors I have brokin in that as long as you take care of them thay will last. and the worst case is I would need to rebuild a motor. OhWell! not that big of a deal for some. thanks

 

You must have a popup blocker or something, I sent you a message asking what oil you used after the factory oil... I would like to know...

Same with me.

 

the ONLY reason your car is burning so much oil is because you v-tec WAY TOO MUCH trust me i was there once....

 

Mobil 1 syn. dont get me wrong my other 2 civics burned oil too. some guys in my area have the same issue. I drive my si but dont rip it up. dont take the triple diget to seriosly its more like 2 time a week. LOL

 

vtec is there to use it!
