Can you use synthetic oil in a new engine?

For the first 1600 km's or 1000 miles on a new engine just use regular oil. The reason being is that you want MORE friction in the engine to help the parts wear properly for a good "break in", synthetic oil has such good lubrication properties that it can interfere with proper engine break in.

How do you properly break in a new 350 engine for a 1969 Chevelle?

If the engine has a flat tappet camshaft you will need to break in the cam first. Start the engine and run it between 2000 and 3500 RPM for 30 minutes, gently changing engine speed between 2000 and 3500. Do NOT let the engine idle while breaking in the cam!!!! If you encounter any problems during cam break-in, shut the engine off, address the problem, then resume break-in. Once the cam is broken in, Change the oil and filter, and simply drive it normally, but don't run it hard for at least 1,000 miles. After 1,000 miles, everything is pretty well seated and the important wear patterns have been established, so you can drive it any way you want.

What is the best speed should you be traveling when breaking in the car engine?

Usually unders 55 or 60 mph and varied speeds. The speed of running in a new engine is really not important. The important thing is, never over rev the engine and never let the engine labour. If you avoid both of these then the engine should stay sound for many miles. modern cars don't need an elaberate break in period. Just don't be stupid and burn out alot or redline every time you shift. Drive like a sensible person for the first 15,000 miles or so. -if its diesel then run it hard. it makes the engine last longer BUT only on diesels, if its gas then take it easy but not granny style


Will a used motorcycle perform as well as a new motorcyle?

I believe every engine is different and there is no way to tell wheather or not a used engine is better than a new or vice versa. A new engine how ever you do have an advantage because there is no miles or wear and tare on the engine but that does not always guarentee it's not going to break down or have problems. Just like a used engine has a advantage or being broken in and the initial problems could be out of the way and running great and may even last longer than a new motorcycle you just never can tell its a buyer's beware market on i believe everything you buy wheather it's new or old.
