What kind of oil do you put in a motor?
Automakers usually specify a 5W-20 or 5W-30 oil for colder temperatures, with a 10W-30 oil as optional for higher ambient temperatures. These three ratings cover most light-duty vehicles on the road. Even more important, though, is changing the oil and filter regularly.

Which engine oil should I use?
Most cars take regular or synthetic oil. Synthetic blend oil is generally required for heavy duty trucks with towing capacity, while high-mileage oil like Castrol EDGE High Mileage is often recommended for cars with over 75,000 miles to improve performance in older engines.
Do you have to use the same oil for every car?
Engine oils aren’t all the same. You can’t assume that the same oil you used for your last car will work for this one. So if you need to top-up, make sure you use the right grade and specification. Why should I check my oil? Which oil does my car need? What’s engine oil viscosity? What are 5W-30 and 5W-40? What are engine oil specifications?
What kind of oil do you use to lubricate cylinder bores?
Motor oil (straight weight or a multi-viscosity oil) can be used to lubricate less critical surfaces such as the cylinder bores. Break-In Oil The assembly lube and motor oil that coat the engine’s internals should protect the metal surfaces against corrosion until it’s time to fire up the engine for the first time.
What kind of lube do I need for an old car?
Racing oils as well as street performance oils that are formulated for older engines with flat tappet cams contain the extra ZDDP and/or moly to protect the cam and prevent premature cam failures. Racing oils also use high quality base stocks and additives that are designed to handle higher temperatures and loads.
What kind of motor oil is best?
Synthetic-blend motor oil is the best of both worlds. It is a mixture of synthetic and conventional base oils with additives found in both. It has excellent engine protection properties at a lower cost than full synthetics.
What does oil do in Your Motor?
That’s because the main job of oil in a motor is to lubricate the metal parts and stop them rubbing against each other so hard that they create excess friction (and therefore heat) and weld themselves together, or simply melt. But there’s more to it than that, because engine oil actually has three jobs to do.
What type of engine oil to use?
Most small engines need 20 to 24 fluid ounces of oil. Small engines typically use SAE 30 single-weight detergent motor oil service-rated SG or higher, but some can use multiviscosity oils such as 10W-30 or 10W-40.
What do you do with motor oil?
Motor oil is used for lubrication of internal combustion engines. The main function of motor oil is to reduce friction and wear on moving parts and to clean the engine from sludge (one of the functions of dispersants) and varnish (detergents).
