Ive been reading alot over at saturnfans that the timing chain will last well over 200k miles if the oil is changed every 3k miles. Ive also read an article on the internet that says this also. If you dont change the oil that frequently you need to get it done around 100k and it runs about $700-$800 for the job. This is completely ludicrous if you ask me that they would design something this way. I'm wondering if anyone here has any input and if I should just go back to running a good dino and changing it at 3000k miles religiously. I would like to keep the car(will be paid off in 1 year) for a long time to use a third car for work(get dirty and do alot of driving) but it bothers me know that if I keep running syn for 4-5k miles then I might need to trade it at 100k and get rid of the potential problem. Any suggestions or input. Car is a 2001 1.9L sohc 5 spd 45000 miles. Had dino first 10k or so changed every 3k miles and syn ever since changed every 4k miles.
