should i change my oil

[harvey05]

hi all ive got a phz1 172 and its got 10/40 oil in it and its sometimes taps for about 5 mins when started from cold i dont use it a lot is it worth changeing it for carlube tripple r 5/40 or would it be a waste of money as the 10/40 is not that old?

Dephaser pully sounds more likely

5/40w is the correct oil matey!! 10/40w is wrong!

might be worth the change as triple r with bosch filter can be had for 32 delivered from ECP
