Hi all,

I was wondering can i use 502, 505 5w 40 instead of 5w30 car is 2014 skoda octavia mk3 vrs 2.0tdi cr. It no longer has a dpf in the car so would this be fine using 5w40?

 

Ok I'll be bad cop:

You know that removing the dpf is an MOT fail right? And one that is being clamped down on.

 

@MarkyG82 If you can't answer my question please don't reply topic clearly says can i use 5w40 not the legality around a dpf. Thanks.

Just why would you use VW502 with a TDI even if doing fixed servicing & not variable.  

VW 504 / 507 is cheap enough.

 

Now if it was a TSI i would be using VW502.

I would suggest one that meets 505 01; and please let us know how it goes. 

@e-Roottoot price isn't the issue, the issue is high oil consumption so thought id try 5w40 slighlty thicker wont burn as bad at higher operating temps as 5w30.

 

@Wino would it be ok using 5w40 505.01 instead of 5w30? Any side affects or is it safe to use in this 2.0tdi cr engine. Thanks.

I service my car every 6-7k

Going 5w 40 FS can help with some TSI's that are not totally gubbed but with your TDI if using excessive oil you have an issue needing addressed.

?

How many miles has the engine done?

There is no issue with the engine have had it fully checked i bought the car on 30,000 miles it is now on 108,000miles it has used excessive oil from the day i got it now it's getting slighlty worse. It used to be 1 litre/2000miles now its at 1litre/750miles. I think its the engine that just burns the oil to be honest.

 

That's why im enquiring about a slighlty thicker oil although 5w40 is a pd engine oil would it be safe to use in my cr engine?

Seems that far gone then that it will not matter what you use

Fill your boots and keep topping up that oil.

Lol i have been and now I've had dpf out thought I'd try a thicker oil see if it helps even if it is a little.

 

What you mean by that far gone there is nothing wrong with it it's just the engine i know 2 other people with same spec car same thing. Cupa engine code. The cuna ones are fine.

Question is will 5w40 be fine in my engine instead of 5w30 even though it don't sort my consumption worth a try?

I shouldn't think there are many people who've tried it, and even fewer who could say for certain what would've happened differently if they hadn't. 

Why not just try it and see if it has any effect on oil usage rate? If it doesn't, no point in continuing, if it does you'll have some data to work with in your decision about the next oil change.

I wouldn't say using 1lt/750miles is "nothing wrong with it". May as well measure oil usage by mpg at that rate.

 

As @Wino says, sounds like not many have done it and as you are using so much why not give it a try. I doubt it would make it worse.

Nice one for your help lads @Wino @MarkyG82
