10w-40 recommended by Honda...
honda say 10w 40. i know a boy that is a top mechanic at honda and he tells me to run 5w 30 its better for the v-tec. and ye my engine fells better. if u look up hondas upgrade oil they do say 5w 30
Cool, I'll trying getting some 5w-30 tomorrow then!
Semi or full?
I have a question, maybe someone here can answer it.
Here in my country, when I ask for a recommendation of oil, they don't watch the honda manual or everything, they just ask about the mileage of the motor, doing this is the correct thing ? for example for my ek9 the mechanic recommended me a 10W 30 oil, the oil was to thin and it passed to the ring and literally I burned oil, after 1000 km I need to put back in 1 liter of oil
So why mechanics choose the oil using the engine mileage as a reference?
Older cars need thicker oil. If you experience oil burns, means your rings aint sealing properly. Your engine must've had a good beating in the past.
I've run;
5W-30
5W-40
10W-40
0W-40
And I have not experienced any loss of oil.
Back to the topic...
5W-30 is better if your country has cold weather. Provides best protection for the street and doesn't take too long to heat up.
5W-40 is better for hot weather as the 40 provides more protection at high temperatures.
0W-40 is best for NEW engines like K20A or if you've had a rebuild. This oil provides Maximum protection from the moment you turn on the ignition.
If you track your car, anything with a 40 figure and no higher than 10W is best. MUGEN has just come out with a new oil that is 0W-40, Bloody expensive! I'd just use Castrol Edge 0W-40 instead.
