It's been quite a few years since I sold my GTS300 - I (kinda) fell in love with a Sei Giorni but I'm coming across many complaints on the Italian and German forums about HPE engines burning ridiculous amounts of oil. A few people claimed that their sump was close to empty after just a thousand kilometres!! Has this problem been resolved or is it something HPE owners need to accept and live with?
One German Vespa owner claimed (on YouTube) that he fixed the problem by using 15/50 oil. I'm not too sure about that even though he managed to do 7000kms across Europe with just one 300ml top-up. Has anyone else done this? I'd like to have a relatively problem-free scooter that can do an occasional long trip across Europe every now and then.
