Engine oil Question?

[furiouswilly]

i got my car service at Kmart using semi- synthetic Castrol oil, so is that 10- 40w? and i have a EK 1 , is mobil 1 5-50w suit for my car? (becoz they are on special at super cheap now for $49.99) or Honda FEO (are this synthetic oil? ), which one is better for my car??

[incoming]

if ur car isnt heavily modded then i'd stick to honda FEO

[aaronng]

Stock is 10w-30 which is what Honda FEO is. You can go 1 grade up, which is 10w-40. And that is as high as you should go. Once your car gets older and blows blue smoke out the exhaust, then you can go Mobil1 5w-50. If your engine is still good and you use too thick an oil, there will be insufficient protection at operating temperature. It won't fail straight away, but it will start to burn oil earlier in the long run.

[furiouswilly]

but is there any 10w-40 synthetic oil??

[aaronng]

Shell Helix Ultra which is 5w-40. Castrol has Formula R 0w-40. 0w and 5w are the same viscosity. Only difference is that 0w stays pourable down to lower temperatures than 5w. The Formula R 5w-30 that Castrol sells for almost 1/2 price of the 0w-40 is a hydrocracked synthetic. The true synthetics that we've heard about for years are the PAO (polyalphaolefins) synthetics (Shell Helix Ultra, Mobil 1, Castrol Formula R 0w-40). The latest one is the ester-based synthetic that Motul makes under the range of 300V in 5w-30, 5w-40 and 10w-40.

Hondas can run 5w-30 (standard for USA), 10w-30 (standard for Aus), 5w-40 and 10w-40 for everyday use on a stock to lightly modded engine.

is this applicable for an eg d15b (Vtec) also?

i've purchased 10w-40. starting to wonder if this was the right choice now.

[aaronng]

Oops, didn't follow up this thread. Yes, you can use 10w-40. The oil viscosities that you can use in your engine are also listed in the manual.

Where can we get Honda FEO engine oil from?? I've beening looking around for some..

[aaronng]

Get it from the Honda dealer (spare parts section). It's about $27 for 5 litres.

[Limbo]

castrol R has a 5-30w which is quite good also.
Mobile 1 also has 0-30w which is $80 for 5 litres
or Motul is good also.

Normal driving just use honda FEO oil. Its only semi synthic though

Mans honestly ill stick to my honda feo ur gonna do a service every 5000KM ryte?

[aaronng]

The FEO that Honda Australia sells is mineral (made by Castrol). In SEAsia, the FEO there is semi-synthetic.

If every 5000km, then FEO should be good. In that time, there would not be that much build up of sludge/deposits/gumming. If you go for a track day, remember to change your oil after as soon as possible.

In the end, it is your money, and some prefer to have synthetic in their cars. :) All of them will protect sufficiently, as long as you use the correct viscosity and service regularly.

HUH? and why would u use a more runnier oil when your car starts blows smoke. doesnt make any sense...
i hope u know what the upper range figure means right

[aaronng]

Upper figure indicates the viscosity for 100ºC, lower figure indicates the viscosity at -18ºC. With our climate, we can use 0w, 5w, 10w and even 15w because we rarely go below zero (if you live in the mountains where it snows, then you'll need 0w, 5w or 10w). At operating temperature, the upper value is more important and a higher viscosity at 100ºC assists in reducing blowby in older engines.

mobile 1 or honda FEO, they both are good enough !!!
i use mobile 1 personally.... :rolleyes:

Agree on the Mobil 1 ....and if I need oil on road trip somewhere, Mobil 1 is very easy to get.

chosing a good oil is a major contributor to your engine's performance and longetivity.

you can chose the viscosity from this chart:

Make sure you use an oil that says "API service SG or SH", this oil is formulated to help your engine use less fuel.
as you can see 5-30 is not recommended in 40C heat in the summer. 10-40 would be the best way to go during winter, and 20-50 during summer.

Super thread revival....
Which car is that chart from? It varies for each model. Here's the one for mine:

You should use SL or SM oils. If you are in a pinch, SJ will work but you might get a little gumming depending on the oil's formulation. Oils from the SG and SH (for engines before 1996) era might gum up under the heat and relatively high compression of current engines.

the chart i posted is for a 94 accord VTi, which has a f22b1, sorry i forgot to mention before. +1 rep for u aarong :)
