[CL9] Is Fully Synthetic bad for an Euro?

The 0w-40 is a Group IV, so it has better high temperature and more resistance to breaking down under harsh conditions than 5w-40. However, if your Euro is driven on the street and not on the track, then it won't matter since both oils will protect sufficiently. If you drive on the street, your oil temperature is about 80-90 ºC. But when you are on track for just 20 minutes, your oil temperature will go up to 110-130 ºC because of all the full throttle and high RPM. In the track situation, 0w-40 would be the better of the two (I have tried 5w-30 on the track and it still protected the engine, but I had to change the oil out immediately after as it felt a little rough. It was smooth again after replacing the oil).

I See!! Thanks!!!!!!!!!!!!!!!!!!!! :D

My head is spinning with all this oil talk :S

I just purchased an '05 Euro that has about 60,000kms. What oil should i put in it, i am happy to spend money on something better? I won't be using it on the track.

Normal drain interval (6-10k km)
*US import Mobil One 5w-30 or 0w-40 (cause they are cheaper than your local supercheap pricing)
*Honda FEO ultra 5w-30 (rather expansive)
*Castrol edge sport, 5w-30 or 0w-40 (used to be good because its so cheap... but they are really expansive now with the new formula)

Longer drain interval (10-15/20k km)
*US import Mobil One Extended Performance 5w-30
*Amsoil 100% synthetic series 5w-30

Any of above will give you better protection than Honda FEO or any of the semi synthetic/dino oils on the market.

It comes down to value. Mobil one extended performance and Amsoil is tested on BITOG to give longer (up to 25k km) drain intervals (ie: optimal protection for longer). So you get more out of your buck. With those oils you could well follow a 12mth/15000km service interval (ala VW/Hyundai) instead of the rather stupid 6mth/10000 service interval.

Me myself I'd personally use the long service oils (Mobile 1 EP and Amsoil) because it gives me a level of comfort, and it cost no more than your average bottle of Honda FEO ultra.

Thanks for that info.

What oil should i put in my 1986 Accord with 240,000kms? It doesn't use or burn any oil either.

Mobil 1 has a high mileage oil you might wanna check out.

Would castrol edge or mobil 1 be alright though?

I just purchased a CL9 2008 Euro that has about 60,000kms. What oil should i put in it? I won't be using it on the track. I am comparing between Penrite HPR5 5w-40 and Penrite Racing 10 10w-40. It says both oils are Full Synthetic. The plan is to change the oil and oil filter every 12 months or 10,000 km. With 25% off at Repco, the HPR5 is now around $43; Racing 10 around $57 per 5 liter bottle.

HPR5 should be sufficient.

As long as you change your filter, most oils are fine (bearing in mind the weight is right)
Just watch the oil consumption

Anyone looking for genuine honda oil filter - check out this seller http://www.ebay.com.au/itm/151026783...84.m1439.l2649

Honda oil filter at the dealer is around $17 + $2 aluminium washer.

Castrol Edge 5w30 is on special for fathers day at Repco $35 per 5 litre bottle (Saturday 31 Aug 2013). I am running Penrite HPR5 at the moment. I was thinking to change to castrol edge 5w30 - is one better than the other for 2008 CL9 accord @60k km?

HPR5 is slightly thicker. I think it is like a 5w-40 from the viscosity in the specifications. For the CL9 at 60K km, both oils work fine.
