Hi Honda fans,

I am new here and have acco 2.2 i-CTDi 2006 Facelift. I bought this car after oil change in dealer, he put Castrol 5w40 and I don`t like Castrol as brand.

As Honda recommends 0w30 or 0w40, I would like change from 5w40 to 0w30(0w40). Has somebody perforemed change like this? Whats was feeling ?
Car has arround 185k km, like 115k mill

According my information it shoud be:

- decrease diesel consuption by arround 0,3-0,5l per 100km
- increate oil consuption by 0,1l/1000 km
- should have better cold starts
- maybe it will be more noisy


I would like to go to Mobil 1 or Motul.
From Mobil:
-Mobil 1 0w40 New Life
- Mobil 1 Turbo Diesel 0W-40.

Have u experience with these oils or with change from 5w40 to 0w30(0w40) ?
 
For the iCTDi 0w30 fully synthetic - nothing else
 
but for 2.0i k20a6 5w40 or 0w30...sorry i'm in your thread but i need to know, this change it will be done with 5w40 but for the next one...what oil type say honda for this engine.
10w40 isn't to thick?
 
For the K20 Honda recommend 10w40. But there are plenty of opinions on different oils, 5w40 isn't that much of a change. The petrol are less sensative to oil compared to the diesel
 
Yes 0w20 is a recent edition and what the engine is shipped with from the factory apparently. But it's a very thin oil, 10w40 seems to work well for my K20 and K24s particularity as mileage climbs

Personally I use Castrol in mine but Lubetech are supposed to be very good value for money. Being in Ireland the shipping isn't with it for me
 
Apologies I was confused with the Cris and Chris responses.

For your diesel I would only recommend 0w30 fully synthetic. Check out the trader section for the deal. I would not recommend 0w40 - so I cannot advise
 
The is circumstantial evidence around using oil other that 0w30 that lead a to timing chain failures in the diesel. Now I've not seen a recommendation from Honda for anything for the iCTDi other than 0w30. But they could have change this.

When ever I change the oil in the diesel I buy the oil from Honda. A full service kit of oil and air and oil filters is €65 over here. The saving of €10 on using another brand of oil isn't worth it in my opinion. However, other members have used Opeoils with great cost saving and success.
 
chris_cl7 i heard that redline oil made in u.s. is very good for honda engines, special for petrol...also good prices... for your engine i really do not know!
also other good brands of oils are amsoil, millers, fuchs, enos etc...better than mobil1 and motul!

as for mine, i heard that the k20 should take 0w20/0w30 better than 5w40/10w40...so, if somebody around here who made this changes with the oils reveal yourself! :p

jay you in yours 2.4 k24 what kind of oil are you using?
 
Chris I would change your oil straight away to 0w 30 you you will cause long term damage to your diesel car.

how many miles you have? from when? did you tried something else?

I have the K24 since 63K miles to 97K now and the K20 from 33K miles to 93K now. The oil works, why change?
 
GET 0-30W and the difference will be immediately apparent. LUBETECH bottom of page, good oil at reasonable prices. Change it every 6.000 and filter every other oil change, now at 186.000 miles no worries.
 
The manual for my 2005 diesel model recommends 0w-30, 5w-30 and 5w-40 as all being OK for use in UK temperatures, suggesting that the design engineers considered all these oils to be acceptable. But I know Honda have since taken to recommending only 0w-30, presumably because the '0w' cold rating would become necessary if you were to drive somewhere properly cold (like Northern Europe?) and the '30' operating viscosity gives less load to the oil pump and therefore gives better fuel efficiency.

I've used 0w30 for the last 5 years and it hasn't stopped my timing chains from becoming noisy.

What service interval you working Jon ??

I've always changed the oil and filter at the recommended intervals, so annually or every 12.5k miles (whichever comes first) and - as you might expect - this was also the regime followed prior to my ownership when the car was owned by a leasehire company. I bought the car when it was 3 years old and, at first, I was really racking up the miles (so oil change every 6 or 7 months) but for the last couple of years it's been an annual chore (around 7k miles or so). I am aware that many owners are keen to replace the oil at a much lower mileage than the above recommendations, although Honda themselves - so far as I'm aware - have never suggested this to be necessary and therefore never reduced this interval on later models.

I don't subscribe to suggestions I've seen (on TA and elsewhere) that shorter oil change intervals would have avoided timing chain wear, and obviously neither do Honda, as the extended warranty was in reflection of poor quality/incorrectly engineered chains and tensioners. I do sometimes wonder if the recommendations for the '30' viscosity are based upon improving fuel consumption and that a '40' viscosity oil may have actually provided superior lubrication? In general, drivers who switch to lighter grade engine oils do often notice the engine becoming noisier, so maybe the opposite is also true?
 
Dunno, brave move I reckon, 5W 40 has almost double the centistoke count when cold, so it could make those crank bearings feel a little neglected. I don't go thicker than 0W 30 myself and I've got a petrol.
 
ciff i do not think is double, can i see some datasheet of the oil you say it's double?
maybe 10-20% more than 0w30 but not double...

I guess it depends upon what you mean by 'cold'.

A '0w' in a very cold climate (not the UK, but certainly Northern Europe) will be more viscous than a '5w' operating in a more temperate climate (such as the UK). So that might make use of the '5w' in the UK look a lot more acceptable?

The '40' hot/operating viscosity rating will give superior lubrication than a '30' rating, even when cold, so I think the crank bearings (at least) will be OK. Where I do have slight concerns is in the flow rates... the '30' will flow faster through the engine oilways than the '40', so may not provide equal cooling to the turbo bearings? However, in compensation, these bearings will now be running in a thicker oil and so be better lubricated. And - at 150k miles - I will have some wear in all bearings, which should then allow the oil to flow faster anyway (whatever the viscosity).

After some thought I've decided to definitely try a 5w-40 in my next change (actually due around now). I'll make a before and after clip of the engine noise and hopefully any improvement should be noted? And I promise to be honest about whether I really believe that there is an improvement!
 
Cris, if you want an example, check out the data sheets on Exol's website. At 40C their low SAPS 0W 30 is 52.5 cSt and their 5W 40 is 93 cSt. It's a lot more however you describe it.
 
cliff, for me exol it's a unknown oil brand manufacturer, but at least i will give you datasheet for an cheap oil but his datasheet promise enough!
exol has nice datasheet...if i will find cheap i will give it a try for their 0w30 next time!
please look here http://www.totaloil.com.au/Pages/content/NT0000C302.pdf and this is not the best of 5w40 but i think the lower 5w40 maybe can get at 40C is 75!
but see it's not half...
also the engine doesn't operate at 40C long time...so the look next at 100C to see the flow! at 40C it's just a pass it's making very fast when it's warming up...
so really what matters more is when the engine is cold, didn't start the engine 1-2 days and the outside temperature is 0C or below 0C and you make a cold start...then yes i can agree that 0w30 is better in this condition than 5w40 but again not by far....the 0w30 is better by far than 5w40 when the outside temperature(how it's saying the mate above) is -20, yes the 0w30 is the best in this scenario, being double!
of course it's playing a role when the engine is 80-90C because this the normal operating temperature of the engine, but here the deference between them is small...and yes anybody can say that 0w30 is thinner than 0w50 even at 80-90C but this can justify the price deference between them? i say is to small the deference between them and doesn't deserve this price deference other than only in colder climates!
also you can study this oils datasheet (also how jay it was saying that honda put 0w20, i do not know the vis at 40c for honda oil) but look here:

1. http://www.redlineoil.com/product.aspx?pid=144&pcid=21 5w40
2. http://www.redlineoil.com/product.aspx?pid=125&pcid=21 0w30
3. http://www.redlineoil.com/product.aspx?pid=124&pcid=21 0w20 and what honda should put inside!


cheers.
 
Exol is available from lubetechshop.co.uk Chris, and TA has a discount code you can get from one of the mods.

Most engine wear occurs in the first few minutes when the car is warming up so those reduced centistokes are important.

I agree 0W 20 or 5W 20 offer even more protection and Honda ought to use Redline! Unfortunately the Honda 0W 20 is semi synthetic which is why I don't use it. And the Redline is too pricey compared to 0W 30 from lubetech.
 
i can not see from where you can take 0w30 from exol - 5l? price?
cliff, i really do not see the 0w30 on their website
believe me that the composition of redline oil worth it's every penny if you go often to red line of you engine!
the oil it's not all about visc...

I agree, the ester synthetics like redline and silkolene pro s are the best there is, I don't push my car hard enough to justify the high price though, but some people do!
