I wanna give the "Hairnet" some spring clean. Oil and air filters, new pads and tyres and get it properly polished. Question is - what oil do I put in? I do not know what's in it now as it was not me who changed it last time. Can I mess anything up by using different type of oil then the one currently used? Thanks in advance.
If you dont know whats in now then i wouldnt top up (just my opinion) replace the lot with 10/40 as mentioned above I use Rock Oil myself
