P.S the magnatec was designed for non-honda cars and the 40w is slightly thinker than what is normal. It will protect fine but will consume slightly more fuel. You might not even notice it but the car will feel slightly lagged.

Firsty Limbo multigrade automotive engine oils are desginated by xW-x(xx) eg 5W30, 20W50 not 20-50W. The W refers to winter and corresponds to the viscosity of the engine oil at 40 deg C measured in Cst. The 2nd value corresponds to its viscosity at 100 deg C. It behaves differently at diff temps thus it's classified as a multigrade oil; which is different to the term "blend" you were referring to.Quote:

Check your owners handbook, Honda recommends different oil viscosities for different climates in the world. No problem with the 10w30 grade in Aust all year; but in North America on the East coast with temp as low as -30 to -40 F in winter running 10W30 most engines would hardly crank over and thus the need to use 0w30 or 5w30 at bare minimum.Quote:

American built Ford Mustangs with the new gen modular V8 for the past 5 years are factory filled with 0w20 oils.Quote:

Actually, the first number is the relative viscosity at -18ºC (0 ºF). W means that they are suitable for winter use (pourable down to -18 ºC).
USA manufacturers are using 5/10w-30 oils now because they can then promote lower fuel consumption figures. It's not because their engines are manufactured to precision like Honda or BMW engines.
Limbo: If you want Castrol Formula R 5w-30 for $30, rush to supercheap auto and pick up the remaining stocks. I just picked up 0w-40 with 20% off for $40 each!
Yes, FEO will be sufficient. Even for track use FEO is sufficient to protect your engine. Before (if your last oil change was close to 6 months) and after every track day always change your oil.Quote:

actually even mr icima... - spoon recomended feo as daily use and even track use (once in a while though) coz they are good oils.. ive been using mobil1 and motul oil but for daily driving just use honda feo oem oil :)
Just to throw another alternative into the fray:
Penrite make a 5w-60, 5w-40, 0w-50 and 10w-50 amongst various others... Is a semi-synthetic and retails for under $40!
I wouldn't hesitate on Penrite 5w-40. But all the others are a bit too viscous for my car. Maybe for an older car with less than good rings. But not for our nice, well running engines.
On the topic of Oils, is it safe to go from Mobil 1 back to Honda FEO?
Reason why I'm asking is because I "think" I read somewhere that once you go Synthetic you don't go back non-Synethetic oils.
thanks.
For a start, changing from Synthetic to Mineral based oil, the engine might not be able to cope with the reduced lubrication from mineral based oil..Quote:

0W-40 increases power fairly obviously however, but not that sure about protection.
There is a new Castrol produce called EDGE which comes in 0W-40, 5W-30 and 10W-60. Fully synthetic, and newer than the SLX.
There is also the normal Magnatec 10W-40 which is mineral based.
The Magnatex 5W-40 (dealer order only variery) which is fully synthetic.
And the one used on Accord Euros is supposedly FMX Magnatec 10W-30 which is semi-synthetic. I know John Blair uses the FMX Magnatex 10W-30 on the EURO as per Honda recommendation, don't know who said they use FEO even though there are bottles and brochures of FEOs at John Blair's.
I think I'm going to try the full synthetic EDGE Sport 5W-30 next time :) As there are no fully synthetic 5W-30 or 10W-30 Magnatec varieties (makes oil flushing a bit hard anyway at oil change, though protective).
Castrol EDGE is the new label for the Castrol Formula R Synthetic(check the website), they also have a 25w-70 or something(for V8's)
I used Castrol Formula R 5w-30 in my girlfriends ED Civic and I give it the BIG THUMBS UP!! Makes it much easier to rev and fuel consumption has dropped markedly.
