I can sit in traffic for 10 minutes and reach 200F+ 
Normal driving is Schedule 2 or Schedule B (depending on the owner's manual). Also, my owner's manual (which I have read) says 7500 oci for that schedule, not 7000  |
Really bro...really? It actually does. If you are waiting for 10 other people to drive through a stop sign your car is getting......HEAT SOAK. Same applies with driving in city with lots of stop lights. Accelerating and stopping creates a lot of heat under the hood VICE driving down the freeway at a nonstop or avg speed where there is constant air flow to the engine, oil cooler, etc. So in theory it has everything to do with it because its a "driving style" compared to someone like me where I worked 2nd shift and I could make a 50 mile trip to work in 55 min without getting below 40mph for 95% of the trip.Only 2 miles on city roads means the car stayed cooler and consistent driving temps made for oil longevity vice sitting in bumper to bumper traffic heat soaking the hell out of the car. Hope this explanation helps. Thanks for the correction on the 7000, I truly meant 7500.
