I went on a 109.5 mile trip and took exactly 5 gallons to refill. My calculations show a average of 21.9 mpg. Is this correct ? The trip was 95%...
The dealers shop manual say that about the weight. Should have clarified in the previous post.
From what the manual says the 10w30 is preferred because of film strength and startup wear.
10w30 or 5w30. 10w30 preferred. It doesn't recommend 5w30 until freezing temps. But the owners manual was written 28 years ago.

Or if I stick with the oem interval , would a synthetic blend be satisfactory ?
Ok. I just checked my local Walmart and they have Supertech Full Synthetic for $2 less than Castrol. Would it be a good choice ? I've had issues...

And what would you recommend for the transmission and differential lubricant wise ?
I'm think of getting the Castrol Magnatec due to it being the cheapest full synthetic at my Walmart. They carry Quaker State Full Synthetic for...
Alright. Which brand should I go with ?
One reason I'm wanting to extend the interval is so I don't have to deal with waste oil as often.
Well the Ultra Platinum is not offered where I live but the regular Platinum is. My owners manual calls for a 7,500 interval using 10w30...
Which one would safely extend drain intervals in relation to cost ?
How do you correctly start a new post ?
