Re: What's your engine oil?
IMO there really isn't that much difference. Theres no real king of the oil world. If you want to run synthetic, it will free up a tiny amount of horsepower and it will allow you to run longer between changes (10k+ miles). If you stick to conventional you loose that little bit of HP and have to change the oil sooner.
Personally, I mostly run synthetic and change the oil and filter around 10k miles.
Re: What's your engine oil?
How many intervals have you passed, any downside or negative effect of waiting 10k?
Any difference in how good of mileage you get using synthetic?
Re: What's your engine oil?
I've gone 15k on synthetic before on a different car. But, I also sent my oil in to be analyzed to see if theres any abnormal wear and there wasn't.
The mileage improvement is going to be very small. You probably won't even be able to tell there is a difference.
Re: What's your engine oil?
I forgot to mention that I had a nightmare last night. I was going to someplace to get my oil changed, and they wanted to charge me $300. After bitching about that, they said ok ok $100. Then I said, ok I'm going to check my prices and I left.
It was a weird dream.
Any recommendations on oil filters?
Re: What's your engine oil?
I'd use a better filter for longer oil change intervals. However, I've heard of a guy running the cheapest Fram filter for 25k miles and getting an analysis back and it was fine. He said he might go 30k on the next filter. I'm not sure how many times (if any) he changed the oil during that time. Like I said, I just stick to doing everything at 10k.
Re: What's your engine oil?
I use 5W 30 in the winter and 10W 40 in summer I use High Mileage oil for my car because it has 92215 miles on it. I want to take good care of it.
Re: What's your engine oil?
:D mobil 1 full synthetic 0w30 advanced fuel economy..... Going 10,000mi This car likes the synthetic in the winter here in MN!
Re: What's your engine oil?
I use Royal Purple 5W30. I have to order it up here though, so when I forget and don't have any I use Mobil 1 Synthetic. I swear by both. I grew up always using Mobil 1 Synthetic. Take a look at how many professional NASCAR teams use Mobil 1 over anything else and that will tell you all you need to know. Just my .02.

That tells me Mobil sponsors a lot of Nascar teams.
