RAV 4 TUNING
INTRODUCTION
Our Rav4 is a 2005 '55 reg 2L d4d XTR with 40k miles on the odometer and has fixed four wheel drive, unlike the 2006 models which don't. With 116bhp the performance is 'adequate' and in reality normal driving requires most of the available torque, with little left in reserve. Towing would be tedious.... Fuel consumption was around 34mpg. Annoyingly, the speedo overreads by 4mph at 30 to 40mph and 5mph above 40. So an indicated 76mph is a true 70 - confirmed by speed via the diagnostic port and by sat nav. The tacho is accurate however.
As with any 'new' vehicle, the first thing we did was to give it a 'once over on the lift at Wansbeck Performance and then change the oil, air, fuel and pollen filters. We used Millers fully synthetic XFG oil, and also replaced the gearbox and transfer box oil. The diff has yet to be done.
ZX1 was added to the engine and transmission and Millers DS4 is always used in the fuel, along with ZX1 once per month. Everyone who has tried ZX1 has noticed the friction reducing power of it on the responsiveness, easy of starting and general 'willingness' of the engine. Using Millers oils and additives and ZX1 gives extra protection a tuned diesel needs. (We recommend changing the engine oil twice as often as well)
