The different fuel grades available in Kuwait are represented by color codes at the pumps. As follows;
RED Pump: 89-91, Regular, Arabic Name: 'Aadi' , 60 fils/liter
GOLDEN Pump: 95-ish, Super, Arabic Name: 'Khasosi', 65 fils/liter
GREEN Pump: 98, Hi-Octane, Don't know Arabic name, 90fils/liter
I use 'Khasosi' on regular basis. I have tried all the grades in my Aurion and found the engine to be smoother and more responsive on the higher grades. The 91 is 89 on some pumps. There isn't much price difference between the 91/95 so I would recommend to use the 95. That is whats used the most here.
It's a common perception here that the 95 is cleaner (as in minimum dust, particulates etc.) than the 91. I say perception bacuse i dont have any facts to prove it.
This is how people in Kuwait decide on what Grade to use:
4 cylinder Engines: Grade RED
6,8 and higher cylinders: Golden
Super Cars: Green
Try the 98 once in a while...you will feel the difference
Just out of curiosity, what region of the US did you import your Camry from? Usually cars imported from South of the US do better. The cars in Kuwait come with a 'beefed-up' engine cooling system and Air-conditioning. So the American cars ment for the Southern states are a better fit compared to the cars ment for the Northern colder states.
Is it V6 or i4?
