Oil

I was wondering if anyone has tried the Rotella for gas engines yet? I am almost due for an oil change and have been using Mobil 1 synthetic since I bought my Tahoe 3 years ago. One time I changed to the high mileage and it seemed my L9H ate that stuff. It was the only time I ever had to add oil between oil changes, so I only used that shit once. However, I have been seeing Mobil 1 isn't what it used to be and have been considering switching to Rotella for gas engines. Should I try it, or keep using Mobil 1? I have around 165k on my L9H and want it to last until I buy a house. Mechanically, there is nothing wrong or even remotely wrong with my engine, just has the 'normal' early morning piston slap. I think this engine may last well beyond 200k

How often do you change your oil? James @swathdiver recently posted results from an oil lab so he might have some advice.

Usually change it around 2800-3500 miles. I do mostly city ciiving.

Mike, you can use ANY oil since you are changing it LONG before its used up.
Also, your engine should NOT consume oil regardless in such a short change interval unless there's a problem.

Look at the you tube about the Amazon Basics full synthetic oil compared to Mobil 1 and others. It won or tied Mobil 1 in all tests. I have been using for a year now with no bad results. No leaks either. no burning of oil. The shit works. I use a Wix long filter.

When I bought it, I used Mobil 1 for awhile and NEVER had to add oil. Sometime last year, I switched to Mobil 1 high mileage to try it out. During that time, I added 2 qts between the next oil change. I went back to the normal Mobil 1 and it has not used a drop since.

I watched a video on YouTube about Rotella vs Mobil 1, and after seeing the comparison, it makes me not want to use Mobil 1 anymore.

I have used heavier rotella diesel in my XJ and it worked great. I think rotella makes 5w-30 now it should be some of the best oil you can use.

Mike, my motor quieted down after switching off Mobil One to ACDelco. As posted elsewhere, the numbers, while not complete, between Rotella Gas Truck and the ACDelco oil are very similar. Have seen some posts where guys mentioned switching over to Shell but can't remember if they gave feedback yet. I wouldn't hesitate if yours were mine. Mine didn't use any oil between changes on M1 or ACDelco. I shoot for 5K changes but sometimes by the time we get around to it, she's traveled another thousand! No ill effects.

I'm still in the process of running my first change with Rotella Gas Truck 5w30 and the longer WIX filter. I almost never hit 5K miles a year, so I end up changing it at that interval. I have a Blackstone analysis from the last oil and will be comparing that to the Rotella when I change it early next year.
