Why is is it that most people discourage others to purchase and toyota with a D4-VVTI 1990cc engine.

In my view if you have the correct plugs they do ( 20,000kms ), do regular service which includes synthetic oil( it does 10,000 kms) the car performs better than most in the same class and consumes less the the VVTI 1800cc.
The future belongs to those who believe in the beauty of their dreams.

@Wa-Meat, (Surprised?),

Some years back,i had a D$ Premio.Didn't last 2 months.Th effing thing would cut off in the middle of a cruise and knock of kila kitu,including the steering pump.....I tried many "pros",including TK.They couldn't solve the problem.Parted with it when i realised it was going to kill me......Along the way,i heard many stories about the D4 engine(true or false).I said never!
Nothing great was ever achieved without enthusiasm.

Yes sensitive engine, but have driven one for > 4 years. Hardly any issues. As Nobby said, watch the plugs, service regularly, fuel wisely (not at those corners). Also found these guys very handy www.opti-ride.com as the guy specializes in gasoline direct injection vehicles (GDI, D4 etc)

I'm at > 20k with the original plugs without much change in performance (great btw).

For the record it is also a VVTi engine. ( http://www.toyotabharat....y/glossary/vvti_d4.aspx )

Infact the next car may probably be another direct injection.

From my own observation, and from what I hear from my mechanics, It is really hard to maintain a D4/GDI engine. Fuel economy is ok with these vehicles but develop engine problems quite fast and that is the beginning of road nightmares. I haven't had any experience with D4 but with a GDI (which use the same technology) and I can confortable say they are bure kabisa.

Your conclusion defeats logic. It sounds like: "I haven't tasted honey and I can confidently say that it is very bitter!!!"

How about putting it this way... I have never tasted KCC but I have tasted Ilara (which is also milk) and I can confidently say Maziwa ni bure kabisa. Hope you get the logic

I have also used a Toyota D4 for 3 years now.good engine,economical on fuel and no major problems to date.but just as the others are saying, always watch out for the simple things like,aircleaner,regular service and make sure it never gets low on the coolant..
Hope is not a strategy
