im not sure about the oil but regarding the jerkyness, i know a friend who has that, but it happens when he is low on rev (1500rpm) ? but i think thats just normal? not too sure . i would like to know too.Quote:

Hi aarong, as soon as the oil light goes off, you have oil pressure and oil is circulating.
Yes the oil is circulating, but give it a while to circulate. I'm sure you can spare 30 seconds for your car.Quote:

If you are in 1st gear, you can actually have the car moving forward constantly with revs below 1500rpm and your foot totally off the throttle, like an auto.Quote:

Im with the other guys on the cold engine thing. The only reason people say EFI cars dont need warming up is because their fueling is handled better unlike an old carby car that is a pig to drive cold. Your engine still needs to warm up so the oil becomes thinner and circulates quicker! Your right in saying you have oil pressure as soon as the light goes out, but the oil is still cold and sludgy till it warms up and thins!
Mind you, I dont wait around for the engine to warm up, I just dont rev it over 2500-3000rpm till it warms up!
The surging problem is quite embarrassing, espeacially when you have other people in the car. I feel it is a engineering issue. And if thats the best Honda engineers can do, well, put it this way, if i knew of the problem before i bought the car, i wouldn't have bought it. I would have bought a KIA. I don't think it's good enough. Sorry about the whinge guys...
Spicey, I know what your saying, but its an old wives tale. The oil in the car is a 10W30. The 10 stands for the thickness of the oil when cold, in a round about way. I may not have worded that correctly, but is roughly correct. Also in the old days they warmed engines up first for the reason you stated but also because they were a straight 30 or straight 40 weight.
Yeah, the 10 stands for viscosity when cold and the 30 is viscosity when hot. The thing I dont understand is why is engine oil thinner when hot even though the ratings state it should be thicker :-S
but meh, each to their own. I will continue to warm up my engine before revving/loading it up thanks!
How long you had the car for???
Bought the car new late december 2003. Surge problem there from day one. Oil use, since 100000 km. before that not a drop. Drive off occurs within 45 seconds of starting, average say 30 secs. Thanx for you input guys. Still like to hear from people with oil consumption issues and or surging when decelerating with a slightly open throttle. The surge is more prominant at 2500 rpm.
10w-30.Quote:

They are equivalent ratings, so 10 at -18ºC is still thicker than 30 at 100ºC.
And yeah, I do the same. I start the car, let it have 30 seconds to idle. In the mean time, I put on my seat belt, check the mirrors, check for kids around the car as well as put the mobile phone into the cup holder compartment. So by the time I am ready, it has been 30 seconds and I just drive off, limiting throttle to a maximum of 1/4 and RPM to a maximum of 3000rpm. My car doesn't burn oil at all, and I even thrashed my car badly by going for a circuit trackday and yet no oil was burnt.
The surging, I agree it is a Honda problem. With the Euros, we even get jerkyness when the cruise control tries to increase the speed and RPM is around 2000-4000rpm. So if the ECU can't get it smoothly, I don't think our foot can. It's Honda's bad.Quote:

Did you try asking your dealer if he put in those "cleaner additives" during your 100000km service? I know our dealer did that to our car without asking once (Holden). It could have removed the carbon that was helping to seal your engine.
