At 18,000km the oil still feel smooth and slippery but somehow it does feel thicker than usuall. A sign that viscoscity has increase. I dont think the oil can go any further, with our hot climate.
So I decide to change the oil. The oil change was conducted at 20,000km..but sorry I dont have any photo taken on the condition of the oil at that millage....just imagine it is worst.
The quantity of Trasko element replace from 0km till 20,000km is 3 piece only without any engine oil change.
Cost:
Trasko element cost : USD9.95 per piece, that sump up to RM104.40 for 3 pieces( 1usd= RM3.50)
Engine oil Mobil 1 = RM138.00 ( I bought it with special discount)
total = RM242.50
Compare to using normal filter replace every 10,000km: RM16x2 = RM32.00
Oil change with Mobil 1 every 10000km x2 : RM138x2= RM276.00
total = RM308.00
Savings : RM308.00-RM242.50 = RM65.50.
I dont include labour charges and other taxes in this calculation as I diy. For those dont like diy...you can add in labour charges and other taxes. Then you can forget about the savings lah.
Today oil change, the last oil change was on 2nd August 2008
Im still using Mobil1
