Frequent short trips by car may cause it to deteriorate. It has been said Alexey Revin, auto expert of Za Rulem magazine.
“Under such driving conditions, not only fuel but also water accumulates in the oil. As the engine cools, condensation forms on the cylinder walls and the drops flow into the pan. Water and oil form an emulsion with low lubricating properties,” he said.
Frozen water in the pan can block the oil supply from the oil receiver, Revin added. Another risk from short trips is the formation of carbon deposits due to the engine running for long periods with a rich mixture and at low temperatures. The car expert also warned that short trips lead to coking of the piston rings and, as a result, oil burns.
Before that, Sergei Zinoviev, auto expert of the magazine “Behind the Wheel” It has been said about the disadvantages of a used third-generation Toyota RAV4.
So the third generation Toyota RAV4 was officially sold in Russia only with 2.0 and 2.4 liter gasoline engines. The engines are reliable, but they are demanding on the quality of the oil. Saving on oil accelerates the failure of the timing drive, and the piston rings are already quite quickly overgrown with carbon deposits.
After 60-100 thousand km, the water pump fails and the crankshaft oil seals leak. In a four-wheel drive system, the sensitive element exposed to penetrating moisture is the clutch bearing. In the steering system, the joints of the intermediate shaft and plastic rack bushings wear out the fastest.
