Rotella T synthetic

[hatcoleman]

Is this a "real synthetic" ??? container does not say it is a blend so I assume it is a full synthetic.
If so it seems like the best deal in town.
$11.95 a gallon
Have used the regular Rottella 15w40 for years in diesel fords. Purchased the synthetic 5w40 to put in gas burners.

Shell Rotella T synthetic 5W40 is a petroleum group 3. Same as Castrol, Valvoline, Penzoil Synthetics.

I use this oil in my gas engine Truck and SUV.

It's a fairly priced group 3.

First time post, long time lurker...

I'm also considering using the 5w-40 Rotella T in two of my vehicles.

The first is a 2000 GMC Sierra with the 5.3 liter engine, with a 3.73 rear end. It has 41,000 miles on it, and is occasionally used to pull a 25', 7000# travel trailer. I change oil every 3,000-3,500 miles. It is used on a daily commute of 12 miles round trip, 90% highway speeds.

The owner's manual specifies either 5w-30 or 10w-30. It seems to me that the 5w-40 would be a good fit for year around use, especially when pulling the trailer. The truck is garaged in a building that rarely drops below freezing, even in the winter.

The second vehicle is a 2002 Honda Goldwing. It gets ridden about 15,000 miles a year, and also assumes a lot of the commuting to work, 8 months out of the year. I change the oil every 3,000-3,500 miles. The owner's manual recommends 10w-40, but allows the use of other weight oils. Unlike a lot of Goldwing owners, I'm not looking for smoother shifting or anything else. Just a good quality oil.

Seems to me that the Rotella T is a reasonably good fit for both vehicles, especially at $12 a gallon.

When it's a Group 4 oil. When it's made from synthetic basestocks. Group 1, 2, and 3 are all dino oil basestocks.

In addition to group 4 being full syn, a group 5 oil such as Redline, made mostly of esters, is also a full synthetic. I know there are some good explanations of what each group means, doing a search might turn some up.
