Which OIL recommended for the B16b


i rev my bike all the way to the 15,000rpm limiter & every time i check the oil level window my oil level drops a bit so i just add more oil to bring it back up. high temps & high revs make the oil very volatile & evaporate which is then sucked into the airbox or intake pipe for cars.

some also get past the rings which are burned in the combustion chamber, as long as it doesn't emit smoke like a 2stroke engine in the morning your engine is fine.

Honda also recommends 10W40 oil on their sportbikes.
 
How about my situation? Temperatures here, varie from -3 most times in winter time, and goes all the way up to +40 sometimes in the summer. Regular summer temps are 30-37. What would be best? i reckon 10-50?? Something else: Has anyone noticed oil consumption in everyday use?
 
i'm using Castrol GTX 10W40 in my EK9, doesn't burn any oil over about 1500 miles as i changed the oil last week and was still sitting at max (usually will do oil about every 2k miles but car was up on axle stands whilst doing brakes so thought it would be rude not to.....)

if i'm out for a long spirited drive i'll generally have the heaters cranked up a bit to keep the engine/oil cooler anyways, although saying that my fan has NEVER had to come on since i got my ek9 :nice:
 
I'm going to try semi-synth 10w30 next, probably Castrol.

I've used fully-synth 5w40 S Pro Silkolene for the last 10k but it seems to burn it too quick. I do drive it hard, though.
 
yeah

I find the Motul 300V 5W40 also use oil regularly if you drive it hard.

guess its not a bad thing? I don't if I should use it again.

the car does feel very good and revs at high rpm nicely.
 
Not a bad thing as clean oil is replacing the burnt off stuff.

The only downside is having to constantly top the oil up! It's not a massive inconvenience though, you've got to expect a VTEC engine to use oil I guess.

Would be nice to go out and check the oil and notice it's still on the max mark for once though, hence why i'll be trying a semi-synth next.
 
I am going to change my engine oil, this is my first EK9 so what would you's recommmend?

5w 40 the best for a daily drive then?

I got told 10w 40 fully synthetic

:nice:

My recommendation is:

Change your oil to a semi synthetic oil, for example motul 5w 40, then change to fully synthetic motul 5w 40. This is just to be sure, my mechanic recommend me this because right now you don't know what type of oil your car has.

:nice:

i think you may find it will consume more with the castrol in it, my uk dc2 used castrol semi synth like mad, also my local honda dealer was using and recomended me BP 0w-40 fully synth which burnt like crazy and the worst by far was mobil1 0w-40 it used to go through like 250ml in about 50 miles when not even driving it overly hard,:shocked: it now runs on silkoline and burns a hell of a lot less, thats the only oil i would ever use now.

also oil pressure stays more stable with silkoline than what it does with castrol which helps
 
Funnily enough I use mobil1 0w-40 in mine and it doesnt use a drop. None at all.

have you ever drove your car hard?:p lol its very unusual for a vtec engine not to burn oil,
 
I just put the car on the road a week ago, what do you think ? I have also been on a long Motorway run 800 miles in a day. Just checked again not a drop used. I do know they are all different don't know why. Some work with an oil that others dont.
 
Went from home near Stroud to Dunfermline to collect my kids plus wanted to see how the car was on a good run as well as the B roads around here. I am loving it guys wish I bought one years ago.

Never is too late as the saying suggests....:) What about your kids? Do they like it or they are too young to find interest in real cars? :drive:
 
A lot of the oil consumption can be traced back to the crankcase breather setup. While it's sufficient under most normal driving conditions, it is definitely not able to keep up under constant tracking/competition environments.

If emissions aren't really a concern and/or you don't mind doing this conversion before going to the track, you can try this method that has been proven to be quite effective without having to purchase many expensive aftermarket parts.

-Remove the PCV valve and associated hoses
-on the stock black breather box, remove the stock rubber tube. There will still be a plastic nipple that plugs into the box.

-Purchase a rubber hose that can withstand the heat/oil
-run a length of hose right off that nipple off the black box

-connect to a "T" fitting - usually made of brass
-run one of the T ports directly into the valvecover breather
-The other T port goes into a catchcan

Now before anybody freaks out and says "I thought you said I didn't need to buy any expensive aftermarket parts!!"

Well you don't. An empty 1L engine oil bottle can be shoved almost anywhere .

The most important thing to remember is the catchcan must vent to the atmosphere - this just means drilling a bunch of holes at the very top so the pressure can escape.

Now you need to plug the open port on the intake manifold and the intake arm so you don't have a nasty vacuum leak.

This is a setup that is used on Spoon's very own racecars when they still competed with the DC2s and EK9s. I had the opportunity to visit both Spoon and Type-One and have a close relationship with A&J Racing where a super taikyu DC2 was brought over a few years ago. I spent a lot of time in/around/under that car before it was sold to a friend of mine in Chicago.

This modification takes about an hour's time if you're going slow and you'll find the biggest time waster is where to place the catchcan. Do bear in mind that this mod will NOT eliminate oil consumption, but in most cases, it will help reduce consumption. If your motor is sick and produces a lot of blowby, it will be evident with the catchcan filling up very quickly.

Spoon uses Motul 300V in varying weights depending on track conditions/temps/condition of motor but they generally have good luck with 10W40. Sorry for my long first post. :p

BTW, don't forget about a baffled oil pan and magnetic drain plug... :D
 
awesome informative post ragingangel, so any more spoon tricks up your sleeve?

what does the magnetic drain plug actually do?
