Hi All

Hoping you can help. I'm about to service my car which I do yearly. I have always purchased 0W30 Castrol Edge Oil from Euro Car Parts for it. It's a Mk8 2011 1.4 Type S.

Although I was looking on Cox motor parts and they have a sale on the full service package but the oil that comes with that is Mobil 0W20 so have I been putting the wrong Oil in my car for all these years?

I've had a look online and can't find much about it some people say one thing and other say another so I can't find a definite answer?

Any help would be most appreciated :)

Thanks
Alex

From the official Honda Maintenance Manual it states that the engine oil you can stick into your car varies from 0W-20 all the way to 10W-40 this is dependant on the expected temperature range you can expect your car to encounter. Obviously the oil ratings are to do with its viscocity at different temperatures.

See the chart below for more details. You should be fine though. You may find that your burn more oil in hotter climates though.



Bother can't upload images until I have more posts...

I'll PM you a link and see if that works...

Your pic works OK.
So for typical UK its 10-30 or 10-40 (down to -20C, and it rarely, if ever gets that cold here).

However my 10G book says 0-20 for European models, so I suspect it's "how long is a piece of string" and I'm coming to the conclusion that 0-20 or 0-30 or 10-30 etc. it really matters not a lot as long as it's not an el-cheapo recycled supply.

Only because I posted another post elsewhere and came back and edited it :wink3:

Just make sure you use something branded, I tend to Use Castrol Edge, Honda Recommend the Shell V-Power Engine oil, other big brands like Motul etc will also be fine. Providing you're within the range of values set by the Honda Chart, you can't really go wrong!

As mentioned above, the oil viscosity chart in the 8G handbook shows that either 0W-20 or 0W-30 is acceptable.

I have also recently spotted this oil recommendation chart from Honda on Cox's website though, which shows that the current advice for the 8G petrol (non-R) is 0W-20 if I am reading it correctly.

My car is currently filled with 0W-30 and I am considering chaning to 0W-20 at the next oil change mostly for extra fuel efficiency, but it may not be worth it as 0W-20 is a lot more expensive!

Honda when I went to purchase oil said 0w-20 for Type R.

0w30 was the recommendation from Honda but they have lowered it to 0w20 in recent years to help with economy. Always had 0w30 in mine and its runs great and don't use a spot between changes.
