Does it really matter what engine oil you use?

Hi all

I bought 15w-40 engine oil (i have a Civic). Is that ok to use?

Yes that may have helped (doh)

Honda Civic 1.8 (petrol) - 56 reg (2006)

What does your handbook say ?

I'm reading on Google searches 5w20 only due to the tight engine tolerances .

Put your reg in here :

Engine Oil and Lubricants Castrol UK - Engine Oil and Lubricant Products

Not sure if the Castrol is the same as any other make .

thanks for the replies mate.

The handbook says use premium grade detergent oil

Highly recommends using genuine Honda Motor Oil ACEA A1/B1 or ACEA A3/B3

Will it damage the engine if you put the wrong oil in ?

That says Edge 0W-30

So does that mean I cannot use anything else or is that just a recommendation?

That is their recommendation , you really need to see what the handbook says as you could potentially damage the engine with the wrong grade oil in , Honda tolerances are tight so needs a thinner oil , hence 5w20

15w-40 means it behaves like a 15w oil at cold temperatures and a 40w oil at high temperatures.
So it's a good bit 'thicker' at all temperatures than a 0w-30.
A 0w-30 oil will give you better protection when starting the engine in cold temperatures.
I wouldn't really recommend you use a 15w-40, unless it's an emergency.

God no. Modern engines need the correct oil, 15w-40 is for old engines and I wouldn't put it anywhere near any Honda engine! If it was an emergency top up then fair enough (any oil is better than none) but don't scrimp on good oil for a full change or normal top-ups. Go to civinfo.com for all the info you need!
