Hey Cary,

I have a 2009 Smart car that seems to be having some issues and I was wondering if you might have some advice on what I should do. I went to drive it recently and the transmission seems to not shift or do anything at all. I put it in drive and the engine just revs, if I restart it a couple of times sometimes it will go into gear and move. What should I do?

Thanks, Phil.

I had a friend ask me recently about my experience with older air-cooled vehicles and what my feeling about the right oil weight to run was. Well, I have driven air-cooled vehicles for many years and many thousands of miles and have experimented with oil to see what had the best results.

Cary,

Here is kind of an odd one for you. I have a ‘71 Citroen D series car and it seems there is an issue finding the Hydraulic Mineral fluid for the system. Do you have any ideas or suggestions for me?

Thanks,

Mark

Cary,

I was wondering if you had any good tips and tricks for bringing an old car back to life that’s been sitting for a long time. I’ve read and heard different things, but I want your advice on what you have ever done.

Thanks,

Tom

Recently I was talking to several people I know about maintenance and care for a couple of Powerstroke Diesel engines and was surprised that neither had heard of oil stiction and the effects it causes.

Hi Cary,

I have a question for you about some maintenance on an older BMW I recently bought. The car is an E30 325i and I was told that it needs to have a valve adjustment. I am new to having an older car as everything I have owned prior has been much newer. Any advice on it and what to keep an eye out for?

Thank you for any information.
