about 15k na since the last tuneup. runs great pa rin naman. starts fine. no problems i have noticed. city idsi 2007 ang car.

All things mechanical will need regular servicing to prevent premature failure of parts. These would include your car. It would be advisable to follow the recommended service interval for your car. It might be running good today but your oil might be the consistency of mud and would require replacing.

A tune up doesn't only replace the sparkplugs. Sparkplugs are cheap (although the City iDSI uses 8 of them) so replacing them at the proper interval should be done to maintain proper operation & efficiency of the engine. The oil (and oil filter) should be replaced as well because oil might not wear out as fast but it does get full of dirt & other impurities. When you replace your oil, what you are doing more of is removing all of the crap that gets into it.


about sa gas.
who uses the e10 gas?
is it cheap because of the octane level? easier consumed? or what?

mas mabilis ba mauubus ng kotse ang 10 liters ng e10? or 10 liters ng regular unleaded? or parehas lang yon?

disadvantages?

thanks sa answers...
I don't use E10 simply because my car runs on LPG. Currently the price is at P27.30 per liter of LPG.

But if I had the choice, I would rather use straight gasoline because I believe that ethanol mixed gasoline tends to result in lower fuel mileage numbers. This is because ethanol has a lower heating value than gasoline. If you are feeling nationalistic though, you can help save our foreign currency reserves & use E10 gasoline. IMHO, the money savings in using unleaded vs E10 gasoline is too small to matter that much.
