I do not know if this has been raised before, does anyone know why there is differences in the Services stated in the Service Booklet and Proton Center Service Manual. E.g - 1. ATF. Service booklet says every 40,000km, Proton Service center says every 20,000km. 2. Spark plug - Service Booklet State every 20,000km, Service center says every 10,000km.

The Service booklet state service every 10,000km, service center says must service every 5,000km.

Which one do we follow, if I insist to follow the Service booklet will the warranty become void. I think this is kind of cheating, sell car, give you a service booklet stating what to service than when you go to service center, the service manual states differently. If there are changes to the service booklet than they must inform the owner of the changes. I may not buy a car if I know I need to change the ATF every 20,000kn while almost all other brand at 40,000km. Maintenance cost maybe one of the factor we may look into when buying cars.

Dear Yngwie
My issue is why the difference between Service center and Service Booklet. Why is ATF change at 20k and not 40k as stated in the booklet. Is the booklet wrong, if the booklet is wrong than they are misleading us. Why you say ATF change at 20k, because the service center says so or proton says so, if Proton said that the booklet is wrong than they must inform us, this is our rights as consumer.

I just service my Rondo for 20k, they do not change the Spark plug or the ATF because their manual says spark plug change every 30k and ATF every 40k. They strictly follow the booklet. Please survey other car makes maintenance schedule and you will discover that most recommended ATF changes at 40k.

The point I'm trying to raise is :
1. When they want to sell the car they say that service is at 10k and whatever schedule service as stated in the service booklet, when you buy the car and sent ii for service than they say the booklet is wrong. Must service every 5k. This is misleading the customer.
2. Car manufacturers are coming up with low maintenance cars. This is made possible by the advancement in Technology. Car manufacturers are coming up with engine that can last 300k without oil change. But proton is making high maintenance cars. Sell cheap cars but charge on maintenance.
