Oil Change – Intervals, Costs, and Useful Information

Oil is responsible for two important jobs in your car. It greases the engine making it run smoothly, and it cools down the cylinders, pistons, and valves. Engine oil contains additives that better the way it performs. Therefore, in order for the oil to do its job smoothly in the truest sense of the word, it must be in good condition, otherwise, metal particles will accumulate in the oil and this gets worse with every mile. Consequently, the lubricating effects decline, and heat can’t be properly distributed causing the valves to deteriorate more quickly.

Fuel temperature sensor: function and failure symptoms

A fuel temperature sensor is a critical vehicle's fuel system component part that measures the temperature of the fuel and sends this data to the electronic control module (ECM). The sensor is typically located in the fuel rail or fuel line and consists of a resistance temperature detector (RTD) that changes its resistance based on the fuel's temperature. The ECM uses this information to adjust the fuel-to-air ratio, timing, and other engine parameters to optimize performance and fuel efficiency.

Since Michelin introduced the radial tyre in 1946, it has become the standard type used in new passenger cars, commercial vehicles, and industrial machines due to the increased driving comfort and fuel efficiency it offers. However, you may still find cross ply or “bias ply” tyres on certain classic vehicles, offroad vehicles, tractors and motorcycles.
