The difference is only 1 dollar and shell is made by pennzoil so i go with valvoline. My trucks are in east texas so its hot except in the winter.

I run Texas Refinery Corp Moly XL Pro-Spec Semi Synthetic 15W40. It's some real good stuff...I've never seen an oil with a TBN this high, mines about 16.8! The stuff even has 3% moly content. They also offer free oil analysis of their oil so I always know what's going on inside my engine. They also tell you when to change it. I always change the filter at 5000 miles, but right now the oil has 18,000+ on it and its still good to go. It costs a bit more up front, but the extended drain intervals make up for it, and so does the free analysis!

I always have used Valvoline Premium Blue, Autozone or Murray's occasionaly runs good sales on it and I stock up. Synthetic oil is nice but with all the soot that you get in diesel oil, I never thought it was worth runnin it unless you had a aftermarket filter setup. They say the soot in diesel engine oil is a big killer and though the oil may not break down, the soot that accumulates is the bad part.

cool thanks for all the help. i was planning on changing it tomorrow. i also just found out i have have a big oil leak. but i dont know where its coming from yet, i was gonna look at that tomorrow too. again its got 240,000 on it

has anyone ever had oil leak problems with those miles? it seems like its coming from the oil pan. what should i do to find it?

OK, I have to ask. Exactly what part of using AMSOIL will I love.

update! well i checked out the oil leak, it looks like its coming from the oil pressure sending unit, so i picked up a new one

are there a lot of problems with the sending unit, i thought ive heard that from somewhere?

My sending unit was working just fine with over 500k when I managed to break it while removing the pwr steer/vac pump
