Engine Oil for the S2000

[yellows2k]

i just use the honda feo oil, it costs me about $25 for teh large container, and it might need a topping up when a 10k km service is due if the car has been driven hard or a track day, but besides that, usage is minimal

Just brought the stock Honda S2K oil... is it true that it's recommended that you check your oil everytime you fill your tank?

Thanks not cool.

Depends if your S burns a shitload oil each week or not.

Mine doesnt at all, but I know some do.

Just thought I'd update you all as I was thinking under the hood yesterday and noticed this but on the Engine Oil Cap, it actually reads to use a 10-30w engine oil.

[AusS2000]

The two numbers represent viscosity or resistance to flow.

Xw-Y

X represents the viscosity at 0 degrees celcius.
w is for winter.
Y represents the viscosity at 100 degrees celcius.

We seldom get to 0 degrees in Aus and 100 is about operating temp so only the second number is relevant.

Now keen natural scientists may notice that the oil seems to get thicker as it gets hotter which is against the natural law of things. That is because it is 'Friction Modified' oil and undergoes a molecular change as it heats up in the range from 0-100C. Below 0 it gets thicker and above 100 it gets thinner.

Here endeth the lesson. Now where's my cookie?

Woah lookout.... the cookie monster is at it again LOL

It's -18 C. So it is even less relevant! (but still important).

[AusS2000]

Ooops, that is correct. It's 0 degrees Fahrenheit which is -18 degrees Celcius.

I LOL a little when people say 0w and 5w are too thin for their engine, and that someone told them to put in 15w for added protection, when they totally ignore the hot temperature viscosity.

Another post asked if he should put in 15w-30 instead of 10w-30 because his engine had many kms on it... I think we need a stickied oil FAQ!

Shell Helix Eco 10 is fully mineral and cheap.
What about Motul 8100 5w-40? Have you tried that one?

Motul 8100 5W40 is oil I've mainly used in the past 4 years. A friend of mine had used it on his DC2R and his S2000. It stands up very well to a good sustained VTEC thrashing IMO.

I've had Fuch's in my S2K and that burned off rather quickly but the Motul has had a harder life but suffered less burn-off.

My friend's Integra used to burn off quite a bit of Mobil1 with blue smoke but that pretty much stopped once he swapped over to the Motul 8100.

These are only a lay-person's observations and subject to any scientific evaluation though.

Do you know what viscosity is the Fuch? Also, was the Mobil1 the 5w-50 in the silver bottle or the 0w/10w-30 in the gold bottle?

[S2kane]

So the mobil 1 5 - 50w is too heavy for the s2k?
