my mechanic told me mobil 1 (5w-40) is too thin to use in my itr and i should use at least 10w as the b18c doesn't like it.
anyone got any expiriences or thoughts about this?

 

I know that Honda recommends that Civic's use 5w-30. Check your manual.

 

Your oil cap should have the recommended viscosity. Being in cold weather where you are, you want something with a low viscosity, to avoid cold start wear and tear. Unless you have an oil leak and he is recommending against synthetics, because the smaller molecule size.

 

I haven't got the stock oil cap or any manuals to tell me either..
I have been looking around on the net but haven't come across anything yet.
I'm in Melbourne, Australia... it's not so cold here.
He said I should use at least 10w-40 but I don't know what the stock item is so i'm a bit unsure now about what oil to use.

 

I saw Victoria and I thought Canada . Well if it doesn't get cold where you are, I would go with a 10W-30. Even if Honda recommends 5W-30, they will still OK 10W-30 in most cases. 10W-30 is better than 10W-40 in most cases because there are less viscosity modifiers in it.

 

i personally recommend 10 40 but you should use valvoline, it works the best, dont bye synthetic just regular valvoline it keeps the motor running real clean

 

also 10w-30 is better than 5w-30 for this same reason.

 

10W-40 is just harder to thin out when running hotter... For all B series I still just use 10W-30 and Honda MTF for the tranny...

 

I use mobile 1 15-50, I think it's good cause my car gets realy hot.

 

all honda should use 5w-30 all year round, it will save you alot of gas mileage.

 

if you want to save gas, then why not go to 0w-20.

or mineral oil?? (0w0) j/k. i like valvoline or pennzoil 10w30. full synthetic on turbo/high comp. apps, conventional on stock/old engines.
also-- if youre a fan of clean internals- i did a little test at work one day. i took a sample of like 10 top name brands of oil and compared them. valvoline is the clearest conventional oil, and pennzoil is the darkest (purebase w/ dark additive pkg.) so thats one reason why im a valvoline fan.

pennzoil, valvoline, and castrol synthetics are made from a group III basestock, which essentially means it is made from dino oil that has been refined enough to be called a "synthetic".

mobil one is made from a group IV basestock which means it is a true synthetic.

 

5w30 you'll lose some horses with 1030 b/c it's thicker. i saw in a magazine with a civic and they did a tune up and changed oil with 1030, then dynoed it, numbers were lower than baseline, so they changed the oil, and the numbers jumped back up. i dunno how accurate that is though, i don't have any real experience.
