Hi Shane10,
Im also using a 2011 Viva Elite. and using nitrogen from day one. I usually pump 25PSI. but once i tried about 28PSI, it's too bumpy and not so comfortable too. then again swiched back to 25. any of you guys on Nitrogen? and whats the PSI?
anyway on fuel, I do pump 95Oct. cos on 90Oct there's a knock. and it does around 11-12Kmpl on Kandana - Colombo.(usually heavy traffic on office hours)
Btw,
anyone know a 3rd party who imports perodua spares?
