Should I buy a Noah with a petrol or diesel engine?



Hi Charity, while you have not mentioned which age and generation of the Toyota Noah you intend to buy, the diesel engines are available only with the 1996-1998 Toyota Noah Town Ace.
I will assume you are looking at that model. The 1998 Town Ace Noah comes with the 2,2 litre turbo diesel 3CT engine and the 2.0 litre EFi petrol 16 valve 3SFE engine.
The 2.2 litre turbo diesel engine would seem to be the obvious choice because generally speaking diesel fuel pump price per litre is cheaper than petrol and diesel takes you more kilometres per litre.
The Noah 2.0 litre petrol engine is also more fuel efficient on the highway (14.2 km per litre) compared to the bigger 2.2 litre diesel (13 km per litre).
In performance terms, diesel engines were traditionally known to deliver a slower response to acceleration, were noisy due to diesel clutter and emitted excess polluting fumes. However, car manufacturers such as Toyota have improved diesel engines and incorporated newer technology such as better fuel injection pumps and delivery systems and turbo chargers.
These innovations have improved acceleration, increased pulling power as well as fuel economy and reduction of emissions or noise pollution. In the case of the Noah Townace the smaller 2.0 litre petrol engine with electronic fuel injection proves more powerful (130 horse power) compared to the bigger diesel engine (97 horse power).
Reliability and maintenance of the 2.2 litre diesel and 2.0 litre petrol engines are easy to maintain with routine.
However, you need to use recommended engine oil and genuine filters, Diesel engines cost more to service as you change both the oil and fuel filter. The 3CT Toyota diesel engine requires strict maintenance and clean fuel to avoid injector nozzle damage. Overall the petrol 2.0 litre engine is more popular and has a better resale value.






Hi Paul, I am past 60 and want to buy my first car. My dream machine is a manual diesel double cabin. Of the 3L and 2.5L; Toyota, Nissan and Nissan Hardbody, what do you recommend?
Secondly, I am also an admirer of the Harrier and Rav4 because of their good ground clearance. Please compare the two, and recommend between the 3L. 2.4L, and 2.2L.Harrier. John.






Hi John, if you are going shopping for a used Toyota Hilux or Nissan Hard body, it will be down to your preference because they are both work horses.
If you find a good Hilux go for the 3.0 litre non turbo diesel engine, it’s easier to look after when it ages. The 2.5 litre turbo diesel engine is economical and responsive if it has been maintained well.
You don’t want to inherit a 2.5 litre turbo diesel engine with a poor maintenance record and a high mileage. The used Nissan Hard body ex Japan or UK may come with a 2.5 litre turbo diesel engine.
A pleasure to drive and very fuel efficient too. With Nissan Hard body get ready for the pricy but readily available service parts at their main dealer Motorcare.
The RAV4 and Harrier Toyotas are not comparable because they are in different market segments.
The RAV4 is a small Sports Utility Vehicle (SUV) while the Harrier is in the medium SUV segment. RAV4 with a small 1.8 or 2.0 litre petrol engines is smaller, easier to park and navigate as well as cheaper to buy, run (fuel) and maintain.
Harrier comes with a bigger budget price as well as higher running and maintenance costs.
In return however you get a bigger and more comfortable 5 seater vehicle which is more thrilling to drive. The bigger Harrier is safer to drive and offers more convenience as well as comfort features.
The 3.0 litre engine is more costly to mainatain compared to the 2.4 litre, however it is more thrilling to drive as it gives you unrestricted engine power. Incidentally fuel economy of the 3.0 litre on the highway may not be very different from the smaller 2.4 litre engine.
This is because the 3.0 litre engine shifts upwards at lower engine revolutions while the smaller engine requires higher engine revs which costs fuel.
I would go for the 3.0 litre engine which comfortably carries the weight of the Harrier.
