Due for another oil change and I want to try a different oil. Not happy with the syn3. Thinking redline. Looking for something to run a little cooler then syn3. I tend to run into traffic to and from work and I hate getting in parade mode. Local mechanic recommends Lucas synthetic oil. From his testing it runs about 8 degrees cooler then syn3. Which he says makes a big diffence. This isn't another oil poll, plenty of them. I've read all of them but still can't decide. Just looking for true hard evidence of testing and experience.
