There is a conflict with manufacturers recommending oils in that some car mfgrs are required by govt to meet certain mileage averages and they know that thinner oils provide less friction and slightly greater mileage. They also know that thinner oils wear out metals faster and your car will wear out faster with the thinner oils. The car mfgs only care ...

I'm going with a leaking exhaust manifold for the ticking. Try tightening the manifold bolts a little. They will have a torque specification but hand tight will have a noticeable affect on the ticking if the manifold is your problem. Go back later and torque them properly. As far as the car running at 2000 RPM on start up, that is normal for most modern cars....

Synchronizers are friction devices. They are most commonly made out of brass although other materials may be used. Brass is a soft metal and as it wears down the power it produces would not damage other components. The synchronizer resembles two cones that fit one inside the other. One cone is attached to the blocking ring and the other to the gear train. ...

Yes there is oil in the system to keep the compressor lubricated. It is carried throughout the system in the refrigerant. It is usually added in when the system is charged.

I would just do the maintenance 500km early. it doesn't have to be all that precisely on the intervals. it's s good way to get more familiar with the new bike. I always do a full oil change I'm taking possession of s new bike, since there is no economic way to know when it was last changed, or with what. getting the oil tested can be done, but it costs as ...

The first number represents the viscosity at low temperature. The second number represents the viscosity at 100C(212F). The W represents winter. The API service classes have two general classifications: S for "service/spark ignition" (typical passenger cars and light trucks using gasoline engines), and C for "commercial/compression ignition" (typical diesel ...

It depends on how much above max. You can read what happens when the oil level is excessive here. Make sure the oil level is actually increasing. Hot oil expands and will show you a higher reading, which is why usually oil level is checked when the engine is cold. If it really is increasing, on diesels this is usually caused by fuel getting into the oil, ...

Someone mentioned rotaries and oil. 5w20 conventional is recommened most likely for fuel economy benefits but this is not the issue with durability. Rotary engines do infact use oil. Typically 1 quart every 3000 miles is normal. This is because the engine has a metering oil pump that directly injects oil into the rotor housings to lubricate the apex seals. ...
