Hi all,
I've been meaning to do a proper introduction but I've not go round to taking any pictures of the car and it really needs a clean before I do that but it's coming.

Anyway, had my car serviced yesterday and the mech used semi synthetic 10w40 oil. I think I went a bit white when he told me this but he's a nice guy and I didn't want to make a fuss so I left it.

The car is a 56 plate 2.2 diesel. Am I worrying about nothing or do I need to get the oil changed again to fully synthetic?

Hi,as far as i'm aware you need 0w30 fully synthetic,honda recomends Castrol.

 

[D_Fizzle]

Yeah, I'll be taking my own 0w30 next time! The manual says 10w40 is OK from -20°c+ and as cold as the UK's been lately, I don't think we'll see that! I'm just a bit worried it'll cause damage so thought I'd better check with the experts.

 

[harhay]

semi synthetic will be ok, dont worry..

 

[F6HAD]

Err, not in a diesel!

I've seen more than one Accord ictdi with a knackered oil pump due to 10w40 oil. Forget the manual, get the oil changed asap for synthetic 0w/30 mate.

 

[JohnnyBoy]

Go straight back and get it changed, like Fahad said, you don't want to risk any damage.

 

[D_Fizzle]

Oh pants! Thanks guys, I'll get it sorted.

 

[harhay]

Sorry I missed the diesel bit........

Hi,

I've seen 5w-30 oil on offer at Halfords and was wondering would that oil be suitable fot the 2.2 cdti's ???

 

[coste1l]

im sure opie oils said it would be?

 

[D_Fizzle]

Just out of interest, how long will it take before pump damage occurs? Just called at the garage and he's not there so it might not get done today. Major problem or ok to wait until he's available?

Also, in your opinions, should he do it for free? Never been through this before!

If anything there will be less wear with the 10w40 than the 0w30.

 

[D_Fizzle]

I understand that's true for the engine but the pump will have to work harder due to the viscosity of the oil being too great, causing strain.

Not true as the motor-oil pump has to work much harder to disperse the thicker oil resulting in poor lubrication on initial start up= MORE WEAR
The journals in the engine are designed for a specific lube??

Its 0w30 for a reason semi synthetic or Fully wont matter but the weight does!!

Some suppliers recommend 5w30 this may help if car is also high miler...

 

[Alanok]

What's the fuss? 10w40, while not ideal will be fine.

 

[delta0]

Honda garages use it too. The higher viscosity will create greater resistance in the oil pump but it clings to the engine better. When the engine gets older then more viscosity oils are normally used anyway.

There's no weight difference only viscosity at a range of temperature. Honda would not put 10w40 in if it was not ok. Oil pumps last a very long time and are designed to cope with higher viscosities.

If your engine consumes oil then 0w30 may not be suitable as it is clearly leaking into the engine which is not good for it. It is worth checking this.

 

[dodger]

The handbook gives a wide range of viscosities for engine oil. In my oprinion if the oil is from the stated viscosities for the ambient temperatures where you live then it is OK.

 

[F6HAD]

People can share their opinions all they like based on technical specs of oils etc but I've been running with the Accord scene for around 4 years now and every failed oil pump we've seen has had wrong oil connected to it at some point in its history.

This thread is pretty pointless as misinformation based on what certain oil sellers recommend will continue to confuse members.

THE ONLY OIL SUITABLE FOR THE HONDA ACCORD/CIVIC/CRV/FRV ICTDI IN THE UK IS 0W/30 FULLY SYNTHETIC.

This may add to the confusion but what quality grade is the 10W40 oil.
