Rotella T Synthetic

[blueoneton]

Just wondering about this? I know some of our 7.3's use some oil between changes and some don't. Mine uses about 1-1 1/2 quarts between changes using Rotella T 15w40.

During next years cold season, I plan on going with the Rotella T Synthetic 5w40. Could my oil consumption increase?


Thanks

It should not increase. It is the 40 part of the oil's weight that you should be concerned while running, and not the 5 part (for cold starts).

Thanks Dave

I was thinking on those lines also. Just concerned. Always hearing sometimes synthetics may increase oil useage. Funny how some PSD's use oil while others don't. Luck of the draw I guess. I was told by a Ford Tech a few years back, some PSD's use a quart or two between oil changes which is no concern according to Ford.

That amount of oil useage is not a big deal, you have 14 to 16 qts and you are using 1/16th of that. A small amount. You should use some oil between oil changes.

Dave,

Funny thing, I was reading some information on Mobil Delvac 15w40. A PSD owner stated his 1996 was using 2 quarts between changes with Rotella 15w40. After changing to Delvac 15w40 no more oil consumption problems. I have never used Delvac 15w40 but I can believe it is an execellent oil. I can't understand how one brand can reduce consumption that much?

That is a good one, bot. I have not heard that one. I am surprised that it would vary that much just by changing from a Syn to a NON-Syn oil. I have heard it the other way but not your way. (Not Wendy's).

I'm trying to figure that one out myself. I guess there can't be a whole lot of difference between major 15w40 oils Delvac vs Rotella/Rotella vs Delvac?

I did notice my oil drain plug has a drip of oil now and then on it. I use the copper type washer, is that the cause? I don't want to over tighten the drain plug.

Look at one of these: FumotoValve.com - Engine Oil Drain Valve - the bast way to change oil , I have one and love it. Does not leak and it it UP and OUT or the WAY. I must admit I don't take my truck on the Rubicon.

I have given Fumoto some thought for a while now
