The mechanic just to con you for their profit, it doesn't matters that you are using fully synthethic or semi synthethic. Actually semi synthethic is good enough, just that you need to service your car regularly. If you can maintain service your car every 5000 km, then your engine will be take care nicely. Service every 10k interval for me consider not that good. Just for example, the oil will getting thicker and darker, how thick it will be if you reach 10k only service your car? Is better that you service your car more frequent then get the best oil but service in double of the time. cheers...
unfortunately they do not offer semi synthetic. only mineral and fully synthetic.i've use mineral before for vios.. the engine performance dropped like hell. its up to personal choice. do you have any document to support your claim or simply giving out your opinion and hope others to agree with you?
if got semi synthetic of course have more option for customers.. but bear in mind that double service (twice 5K service) for semi, the charges will be more than fully (10K service).
coz i've compared mineral services charge is equal or slightly less to fully synthetic charges (for major services and normal services after 1 year)
