Well on 1,000km check up in Feb 2005, Toyota guys said the oil was ok and no need to change.
Since then I am chaning oil+oil filter after every 5,000 Kms (usning Toyota Motor Oil) and air clearner after 10,000 to 15,000 kms (depending if it gets ok after air spray).
Generally I have been going to Toyota Islamabad motors for all maintainance after four-five months. Prices of Oil and airfilter have increased at every visit, but there was decrease in the price of airfilter.
This is what they charged last week:
Labour 100 rs for oil changes (unchanged)
Oil filter 595 rs (was 425 in Jun 05)
air filter 810 (was 1025 in Jan 06)
Engine oil 1050 (was 750 in Jun 05)
In February 07
Oil filter 583
Oil filter 475
In January 2006
Oil filter 460
air filter 1025
I thnik that it's time to go back to regular caltex oils and Guard filters as 3S is costing too much.
