I just had a guy who installs satellite dishes tell
me about using Mobil1 10w30 in his ram. He said he
was told not to change this oil at all, just the filter,
because Mobil1 never broke down. So over a period of years
he just changed the filter and topped it off with a new
quart of Mobil1. Sound strange? It did to me. He said he
put 118,000 miles on the truck before it was traded in and
never had a problem. There is no way I would do this to my
truck, I'd swear it was a sales pitch if I didn't know what
the guy did for a living.
I think someone on the DML posted that Mobil1 was a man made
hydrocarbon based oil who's viscosity would break down after
9000 miles. Something was also said about polymer based oils
(like Redline, Royal Purple) not breaking down and just getting
dirty. Anyway I relayed this info to this guy who just shrugged
his shoulders and said again, he never had any problems. Makes
you wonder how much money we throw away on this stuff. I've
thought about adding 1 qt. of Redline or Royal Purple to mobil1
just for added protection, mpg and maybe change the oil every 5
to 6K miles instead of the regular 4K interval. I can't afford to
go with all polymer oils $10 a qt.X 5 = $50 bucks, $60 with the
Mobil1 filter and change it every 4K, I love the Dak, but geez.
