I have a track only 2000 Civic with a jdm b18c-r that I trailor to the tracks. Stock Pistons with hasting rings, stock valves and springs with ctr cams. No Oil cooler but my catch can does have a return to my Moroso pan.

Here is what I do with the car, Every monday I do 4 20minutes lapping session with 30 minutes between them. I have entered 3 regional races that are coming up in July and August (Calabogie and Mosport)

What motor oil should I run???

Cheers

i ran the royal purple 5w30 and fell out of vtec on the track mid session, i wont run royal purple on the track again

used Amsoil 10w40 and i didnt burn a drop on the track and the motor ran strong throughout the day

ive heard a lot of people recommend the castrol gtx 10w40 (im pretty sure thats the one)

i'd recommend something in a heavier weight. i run mobile1 15-50, Redline 50wt is also good.

At the end of a 25 minute session my oil is very thin, but the pressure remains constant.

My biggest concern is Engine life. I have 3 hours of dyno and 2 hours of track only...was using regular 10-40 oil since I was breaking in the motor (Compression when cold is 230-235 so I'm assuming the rings are good do go)

I want my motor to last the season.

(full Fluiduyne rad, samco hoses, upper deflecor plate, Mugen thermostat and fan switch, bypast the coolant so it doesn't go to the TB and IACV, ceramic coated AEBS Intake Manifold, honda intake gasket, Endyn breather kit to reduce crankcase pressure plus a Fluidampr crank pulley are my current reliability mods)

Patrick,

It's Mark...Sup buddy. I run Motul 5w40 in my car. You can run the 300v which is pure ester based and a GREAT oil but expensive or the 8100 which is a very good oil as well. The 300v being pure ester based doesn't have alot of the additives that other synthetics do, because of that you tend to burn pretty much no oil at all as the those additives are not there to burn off at higher temps. Just my 2 cents. Hope everything is goin good man.

That's interesting. I'm having difficulty getting a D16Z6 to run for full sessions. I keep getting oil pressure at VTEC code in some sessions. I might change to a little thicker oil and better brand. For what it worth, I heard good things about the Valvoline Race oil (sp?). It has all the ingredients of Amsoil but not the cost, which is probably by not being synthetic.

Amsoil makes great oil, that's what I use in my race car. I even had blackstone labs do some oil analysis after 3 race weekend on the same oil. It held up great, and they said the oil could of been used for even more races before it needed changed!

Amsoil (5w30) is good stuff. Lapping day in 75 degree weather.... (4) 20min track sessions.... Didn't burn a drop of oil

bosco500

Just a heads up, the seller rock4dad is selling cases of RP 10w40 on ebay for $70 shipped. I just picked up a couple, looks like he has about 10 left.

I'd rather Pay Full Pop Retail for MOTUL! Than have any of the other crap for free!

Has anyone used the amsoil dominator race oils? Looks like its offered in a 10w30, 10w40, 15w50 . I'm currently on mobil1 5w30 and thinking about switching over to amsoil on the next change.

I'm not burning oil too badly. Maybe 1/2qt over a a 3-day weekend but would be great to have something that held up a tad better.

welcome to the fun world of the d16z6..........

Mobile1 and redline in the above mentioned weights will do it for you.

really, that's scary. but have you used there heavier weighted oil? like there 10w40(or was it 5w40)? would think that it would be a weight issue for your oil since you changed it to a 40 weight.

clem kevin

the weird thing is that it happened on a straight, not a turn. So it was obvious the oil was thinning out. It sounded like i hit the rev limiter at 6500rpm (gsr) and it scared the poop out of me. Added some oil and sat out a session and it ran ok after that. I dont doubt the quality of royal purple, ive hung out with one of their chairmen at the head2head series for torque.tv, but for track their 5w30 wont cut it.

Im sure using one of their heavier weights would work, but until this last week i never found anything above 10w30 in the local kragen/autozone/pepboys

Whatever oil you choose remember to use a viscosity that's as narrow in range as possible. Ex. 10W-30 instead of 5W-30, 15W-40 instead of 10W-40 or 5W-40. A narrower viscosity range means less viscosity modifiers, which means a more stable oil at high temps and for longer.

I'm basically one weekend away from giving up on d16z6s and put something else but I hate to leave ITA. Do you know something I don't? I never had problems when I ran a CRX D16A6 but this D16z6 has been nothing but headaches.

As far as oils, what experience have you had? Is there brand/weight that has worked for you? ....At this point, any info would help!

saying that, don't they make like 0w50 race oil? or am i on crack?

Any number of us here will tell you that Mobile One burns in high revving Honda. I'm not sure why. It just does.

A companion drives his B motor ITR with me at most track events. Over a three day period that will have about 14 sprint sessions total, he will use as much as three quarts of Mobile One.

The last time we were out, he had switched to Amsoil 10 W 40 and didn't use a single drop.

This is in a B18C5 with very high mileage.

I have been using Motul 300V 5 W 30 for a couple of years. It appears to be very good. I'll not only have a full crankcase at the end of one of these long three day events...but the oil won't even change colour.

The down side is that all Motul is very expensive. Most of us are too paranoid to leave the Motul as long as it's probably going to be good, and this makes the frequent oil changes on a track car a significant part of your hobby's budget.

For this reason, I would consider using Amsoil 5 W 30 or 10 W 40 simply because it's cheaper and because (like Motul) it does not burn after three days of heavy use.

Just one old guy's opinion. :-)

Actually, now that I think of it, Tom Fowler from OPMAutosports uses and recommends 15w-50 in all his Honda race motors.

Please, does he recommend that weight for the oil brand that he is using, or for all brands?

Actually, I don't know what brand. The reason I know is because the guy that bought my old ITA CRX, had work done by Fowler and that's what he used in it. I'll find out what brand.

I'd be interested in knowing.

If he is recommending that for Mobil One, I would not be at all surprised.

If he is recommending that for Motul 300V, I would be very surprised.

I don't believe such an oil exists. Real racing oils are straight weight, ie. what's used in F1. All the fluids are brought up to temp before the engine is started.

There isn't a need for good cold cranking properties in a racing/track application.

unrealwrc

I run 5w-30 mobile 1 in my heavily built b20vtec. maybe 1k miles on the engine and does not burn a drop of oil at the track. I have been to 3 track days so far this year and an auto-x and the car never gets driven on the street except to and from the events.

Seeing what you guys are saying though makes me second guess my oil choice. its non-syn and the oil I just replaced this sunday (after 500 miles) looked pretty dark.

Should I run 10w-30 or 10-40 no matter what syn or non-syn for racing applications? even if I don't loose vtec or burn oil?
