Just got a second oil change at 6600 miles and my friends recommended that I put mobil one 15w-30 in my car instead of 5w-30. I have a jdm header and aem cold air. Is this ok. They said b/c my car gets a lot of abuse that thicker oil will protect it more. Please give your honest opinions of my friends and flame if u want b/c I still have a free oil change from acura and if thats not the right oil I'll bring it to them for another oil change. Thanks

 

15W-30? I didn't know Mobil 1 existed in such a weight. Oh well, I use Mobil 1 10W-30 and have never had any problems with either one of our R's. If you're speaking about 15W-50, I think that is too heavy for our motors. We'll have to see what others say. I believe this has come up before on the board.

 

I personally wouldn't stray any further from factory specs than 10W-30. It's what I use for street and track, although I won't back this up with any facts or even my own personal reasons because others will argue no matter what you say. Just my $.02

 

i'll stick with factory 5w 30

 

Thanks for the responses

 

10w-30 isn't thicker than 5w-30 after the engine warms up.

 

I stick with what the factory recommends, 5W30. I use Mobil 1 or Pennzoil Performax (full synthetic).

 

5w30 for me or 0w30


Boba- who needs to change his oil in his bike this week.

 

****** don't ride bikes.

Oops, wrong thread.

 

ROTFLMAO

 

****** do ride bikes. Man ya'll are a tough crowd.


Boba- whod like to go to the expo and race all the R's and NSX's on his bike to see who can keep up. NOBODY!

 

If your car is Turbo'd or SC'd...15w-50 in the summer...10w-40 in the COOL seasons...10w-30 during FREEZING times.

 

how bout 10w-40 then? heh-heh

 

boba...what kind of bike you got? I have a 99 ZX7R, need to get a new GSXR 750 though...my buddy just got a GSXR 1000, thing is FAST!!!

 

I have a 2k CBR 929RR with a nitrous kit on it.


Boba- who has to go drop the bottle off to have it filled for this weekends racing.

 

nice bike...Did you get the yellow and black or red and white (those were 2K colors or 2K1) you are NOS happy aren't you? ( I think someone should get Boba in F&F II ) hehehee

 

I actually had my bike painted the same color as my R, Flamenco Black Pearl. The bike now looks a little like a 600, but mostly everyone that i race knows that its a 929RR.


Boba- who's dealer thought it was crazy when he bought the CBR and immediately took the stickers off.

 

I was going to paint my previous bike (97 F3) Championship white...hehehe that's funny

 

...Type R. Just gotta get that trunk spoiler.

 

I've always considered the Yamaha YZF-R1 the ultimate sport bike, but since the new GSX-R 1000 came out I have to admit that I think the R1 has been dethroned. The GSX-R 1000 ******* RULES! FAST AS HELL. Words can't even describe.

 

DAMN FAST BIKES now I want a replacement for my slow assed TL1000R.

Btw why can't Honda put VTEC on their bike engines.

 

I don't know about forced induction cars, but the factory recommends 5w30. I use Red Line 5w30 street oil which actually provides a higher film strength than most 10w40s. They are the best.

About bikes, my personal favorite is the Ducati 996R. If I am not mistaken Ducatis have won almost every FIM world superbike title since they were introduced. Now that is a racing pedigree. Not the fastest on the street but it is where it matters...the track. Moderators, sorry for going OT but I truly love Ducatis.

 

For track events, I use Redline 10w40. I used to use Mobil1 10w30 and I always lost a lot of oil after running a few 25 min sessions. But with the 10w40, very little oil lose. Someone at the track actually recommended that I use 10w40.

 

Dood talk about off topic... haha motorcyles...

Anyhow, as I understood it, 5W-30 is used in winter climate because it's thinner at lower temperatures than 10W-30 or 10W-40. The drawback of course is that at high temperatures it is thinner than 10W-30. Now this doesn't seem to be a problem since Acura recommends 5W-30 for all climates.

Running a thicker oil while offering more protection probally will lower gas mileage and reduce power. It's just a matter of more fluid friction (viscosity). I am kind of considering switching to mobil's 0w-30 to see how it feels in my car. Even less protection, yes, but at the same time I think all the oils that Mobil offers provides more than enough protection. Of course, I don't have a 9k redline or a turbo...

 

come down here... I'll find the video of Darren's Supra(800whp and change) kicking the **** out of my friend's 130somethingwhp 900RR that's been lightened(roll on from 60mph I think) ... Supposed to be a vid of him putting six or so cars on a Haybusa... I'll wait to see that one before I believe it though... interesting car... seems I remember that there is a blue bottle on top of that figure for "special" races.
