Hello everyone, this is a great site. I just joined, and am looking for some advice. I bought a 2002 rx300 about a month ago. I noticed that it was using oil, hard to determine exactly how much at this point. I removed the valve cover, and everything looks good with no signs of sludging. The car has 90k miles and was well maintaned. The car was a one owner and they gave me a copy of the service history. I am planning to do an oil and filter change, so I will be able to determine oil consumption. I have done a lot of reading about the oil to use and it seems like mobile 1 or castoral full senthetics would be a good choice. I am a little confused on whether to use conventional or synthetic. I know the previous owner used conventional. To sum up, my main questions are as follows. Thank you.
Should I go synthetic, if it has been running conventional?
Is there a diffrence between oil filters for synthetic or conventional?
Is there any information from Lexus stating wheter to use syn or conv? (i have found nothing in the manual)
