I'm surprised no one said anything about your brake fluid. Difference between DOT 3 and 4 is its boiling point (4 is higher). There are also differences in formulations of course, but the DOT rating refers to boiling point only. Remember that boiled brake fluid is ruined and must be changed. Our brake rubber catches a lot of flak for being unable to stand up to common DOT 3 products. I think it's merely a function of being 26 years old, but that's flame bait for another thread. Just to be safe, however, I do run a synthetic blend DOT 4. Less expensive brake fluid is glycol based. Pure silicone formulations are available, but they will not mix with residual glycol fluid. Synthetic blends, however, do mix and seem to be a nice middle ground (kind of like ester oil in the A/C rather than PAG). Regarding your spark plugs: I run Delco R42's myself. It's a nice mid range plug for all driving conditions. If you plan to upgrade to high voltage ignition, I definitely recommend Delco's. They hold up extremely well (better than exotic plugs IMHO). Remember to use your spark plugs to indicate conditions inside the combustion chambers. Bill Robertson #5939 >--- In dmcnews@xxxxxxxxxxxxxxx, "T.
