Oil change is comming up, and I only want the best for my baby

My driving style is mostly street driving, but I take my car to about 5-6 trackdays during summer.

I've been running castrol rs 0w40 and 10w60 in the past. The 10w60 seem to work fine at the track, but lasts no more than about 3000km before its broken down and oil consumption get crazy high. The 0w40 is fine at the street but burns when at the track. I change my oil about every 5000km regardless of how many trackdays I've been at (I live in the city so I cant just change the oil whenever I want to).

So, at least here in Europe, I've been recommended to try the mobil1 5w50 or the 0w40. On the paper these oils have way superior specs to the castrol rs oils (Pour Point, Flash Point, Fire Point, Total Base Number, Sulphated Ash content etc etc).

But when I search the archives here I see lots of you US guys are complaining about burning a lot of oil when using the mobil1 0w40. The 5w50 I can't find anything about in the archives, so I take it you don't get that one in the US?

So what should I do? Should I look only at the oil specs and buy the best one (mobil1) or what? I get kind of nervous reading about so many US people burning lots of oil using the mobil1 0w40..... Are there other factors to the oil than what you can read on the specs?

 

The oil sold in Europe is far better than the versions that are available here in the states.

You might be able to get some here here. :rightarrow: http://www.bobistheoilguy.com/

I am not sure if they have info on Euro oil... but you might check and see.

 

mobil 1 is good oil...the tech's at mobil 1 said their oil doesn't start breaking down till past 500 degress's F... a lot hotter than an engine runs from what people say.

 

If you want a oil change that you can feel this has been my secert oil change in my car for a year now but ill let you in on the secert.

3.2qts. mobil 1 10w30 plus 1qt. Lucas Pure SYNTHETIC oil stabilizer with a K&N oil filter. equals power you can feel trust me on this one.

also dont be stupid and buy a mugen oil filter like i did cuase its a fram! only unless entering a jdm class car show!

That's correct.

These are the viscosities of Mobil 1 engine oil currently available in the States, as noted on the Mobil 1 website:

No need to be nervous. Many ITR engines burn oil, without anything being wrong with them. Don't be nervous - just check your oil level frequently, and add more if it's low.

Hi, .RJ!

 

So basically what you are saying is that I should just buy the oil which has the best spec on paper? There's nothing more to it than that?

They are complaining about the Mobil1 5W-30 or 10W-30. I haven't seen someone using and/or complaining about Mobil1 0W-40 yet.

You should also check the Castrol TWS 10W-60, it's the old formula syntec from Castrol. Maybe it's for track only.

I used the TWS all last season. It works well for track, but in my experience it doesn't last very long when used for street driving (3-4000km max).

I don't have the opportunity to change oil after every track event so I need an oil which can take a bit of beating at the track and also perform well at the street.

 

The TWS 10W-60 is not the same as the RS 10W-60 anymore:

http://www.castrol.com/castrol...00252

Some countries have both available.

 

btw, anyone here who know how to analyze oil based on specs (Pour Point, Flash Point, Fire Point, Total Base Number, Sulphated Ash content etc )??

I'm currently using this:

Someone who can compare it to the finest mobil1 oils?

Nice

 

if its porsche approved cant be that wrong.

but what i don'T understand

5w 40 they re burning

and 0w 40 not? its even thinnner....

but i ve the same when i ran 5w 40 i burned oil, now i m running stock 10w 40 and nearly no oil burn after 5000 km....

so whats going on?

but i m thinking to use castrol rs 10w60 next time.

 

just because a Porsche is fine with a 15w 40 dosnt meen its going to be the best oil for every other motor. I'm pretty sure the recomended oil for Integras are 5w-30, and thats what you should be using. Espeically if you drive street all the time. Sure you wont notice anything if you use a significantly thicker or thinner oil, but if you keep using it over time, your motor obviously wont be in the same condition it should be. If you run track all the time, thats a different story, because your motor will probably be alot hotter than what it normally runs, which will call for a different viscosity of oil.

remember these guys live in europe where the government does not dictate what viscosity should be used. they are "allowed" to use multiple viscosities at varying ambient temperatures

i believe their recommended oil viscosity is 5w-40. this happens to be the same for japan too.

wrong, wrong, wrong, wrong and wrong.

search for the oil threads in the ITR forum - there's been some very good discussion in the past if you want to learn more. If you dont, thats fine, just dont spread misinformation.

 

Have you considered using Valvoline VR1 racing oil? It is 5w50 full synthetic or 10w60 blended, both available in EU:

Very similar specs to the Mobil1 5w-50 which also is avalible in the EU:
http://www.mobil.com/Norway-En...0.asp

The Mobil1 is in addition MB 229.3 approved which means it'll last a lot longer before breaking down during regular driving.

Have you ever seen a porsche with 200-300,000 miles on it? I havent.

Actually, I agree with EVERYTHING Silverbullet86 has said. The fact that you don't, .RJ, is a matter of opinion, and my opinion agrees with Silverbullet86 and differs from yours. Just because you have a different opinion from someone else's doesn't mean that you should claim that that person is wrong. He's not wrong, and what he says is not "misinformation"; shame on you for claiming that. He just has a different opinion from yours. And his opinion is every bit as valid as yours.

The oil viscosity recommended for the ITR in North America by Honda, as printed in the owner's manual and in the service manual, is 5W30 at all operating temperatures (preferred over 10W30, which is also noted as acceptable in the manual for ambient temperatures above freezing). Just as there are multiple viscosities stated in the ITR owner's manual in Europe, with no viscosity labeled as preferred. What the owner's manual says is a matter of fact, not opinion, and can be verified by looking in the manual. Silverbullet86 is correct in stating what the North American manual says.

Any suggestions for using a viscosity other than what is recommended in the owner's manual is simply one person's opinion. My opinion is that it is best to use the viscosity recommended in the owner's manual. My opinion is that I have not heard any reason that makes me want to use any viscosity other than the 5W30 recommended in the owner's manual. You are welcome to have a different opinion, and to use whatever viscosity you want in your car. I will continue to use 5W30 in mine.

One person's opinion can be different from another person's opinion. A statement of opinion cannot be wrong.

It's just friggin' oil! Unless you see a lot of track duty, the worst that can happen is that you spend too much money on an oil change.

Have you looked at the Mugen line of oils? I heard it's worth 2-3 HP.

Yeah, the real free world is Europe. You have the freedom of choice here in Europe. That's my opinion.
