I do change my oil and filter every 3,000 miles.
Gotta love those beautiful Snookies! I pretty much target Snook and Reds year round. Nothing like inticing a snook to come out of the mangrooves...
FTW, You will not have any issues with breakdown of any oil you change at 3000 miles. Many would agree the normal weather conditions of Florida (high heat pretty much year round) should be considered "severe duty maintenance". But with the tight tolerences of todays motors, running 5w-30 could be the reason you lose that mile or two. Its designed to run fully protected with 0W or 5W-20. Your making the motor work harder to "slush" the 30W around when hot, like most of the time here. Even though we are fine running with 5W-20 in FL year round, running 0W-20 will always help the motor on "cold starts", and over the long haul better gas mileage results. I have always been a 3000 mile oil change guy, and ran good quality dino oil, but I decided to go to 0W20 full syn for two reasons, better quality oil for the motor and the ability to run 5000 miles per oil change without worry. I figured every 10,000 miles or so I would do 3 oil changes with dino, and with full syn only 2. So, at the end of the day the cost of oil changes is about the same, but I feel I am protecting the motor as good if not better, and I only do 2 changes every 10,000 miles which is better for the envroinment as well.
