6.5 diesel

[Anthony1]

I picked up a suburban with a 6.5 and 212k on it. My question is the guy was running delo 15w40 in it and I was going to switch to Schaeffer's Synthetic 15w40, will it be OK? The engine has never been apart and runs really good and has all the good aftermarket stuff added.:redneck

Run it..... The 6.5's have a very large journal crank and they can take allot of abuse..

Thanks :awesomework::beer:

Why wouldn't you run it?

Synthetic oil is so much thinner. I was worried the engine may not have enough oil pressure or be properly lubricated being it has 212k on it. I'm just a idiot and don't know ****. That's why I asked the question better to be safe than sorry.:redneck:

I ran synth in my 200K Toyota 22RE for a while. No issues. Changed it once a year and the filter ever 6 months.
