Hi everyone, I'm new here.
I have a 2009 Hummer H3 with the 5.3l v8. I think GM calls it the LH8 motor. It has 69k miles on it.
I have owned it since 47k.
My dad owns an oil change business.
For the past two years we have been putting in this oil that he gets in bulk. I believe it is Coastal 5/30 Synthetic Blend. But I've been wanting to go Full synthetic.
I change the oil every 3k miles
2. I don't have the owners manual. But I'm pretty sure it doesn't require full synthetic. Oil cap just says 5/30 SAE.
3. I live in Arkansas.
4. I mostly drive easy. But sometimes I'll step on it and get it up to 4K rpms. Lol
5. Daily drive is mostly short trips and city driving.
6. No real issues. It did use about 1/2 qt of oil last oil change.
I recently switched to Pennzoil Ultra Platinum 5/30. I also got their platinum oil filter. Anyone know the difference between platinum and Ultra Platinum?
But I read that entire "Oil University" thing and it got me thinking about a 0/30 oil.
