Hi there, this is curlp8's wife here. He is working night shift tonight and asked me post on his behalf. After reading this thread he checked his compressor oil. Just a wee drop on the dip stick. Not dry yet. We went to our local toyota dealership and asked to order more oil. The chaps there were really nice and told us they would let us know when it was in. Later on this afternoon they called, whoever they were ordering it from got really short with them and pratically refused the order the oil. Claiming that it should not need topped up. The men in our local garage then called us back in to give us a print out of stuff they had been sent, showing how to check, and change the compressor oil. On this it states that you should not fill to any more than half way up the dipstick. Sorry for the ramble but he just wanted to let you know don't over fill. I'm sure curlyp8 will keep you up to date on how we get on...
