Hey everybody, on my camaro I have "free" oil changes every 5k miles up until 30k miles (so 6 total obviously lol)..the dealer gives me 8qts of Mobil 1 and a filter and I change it myself. I have 8500 miles on the car. I changed the oil at 1500 miles...and then at 5k miles I used my first free oil change. Now where I need your opinion is since they give me the oil and I change it myself should I really change it at 5k miles? (i mean the oil is free)...or when I get to my next change interval at 10k miles should I just get the oil and not change it until the olm tells me to? Or maybe change at 25 percent or so? Potentially if I do this instead of having 30k miles worth of free oil I could stretch it out to 50 or 60k miles before I would need to start buying oil. I would rather use Pennzoil plat or ultra...so I'm not sure if I should use the Mobil up in the first 30k miles or just use it as long as I can since its free..thanks for any advice.
