Sounds like your mechanic is an idiot - sorry to say. Can't possibly think why he's giving that advice out to anyone running gas or diesel these days. The ONLY thing I would consider running straight 30W oil is my lawn mower!Had a VW mechanic tell me today he prefers running a straight 30 weight versus 5w-30. Anyone doing this? What are the veteran diesel owners thoughts?
Thanks as always,

SAE30 oils are still common with small aircooled gas engines like those found in outdoor power equipment (OPE). Still spec'd and used in old diesel engines too.Were would you even get straight 30 weight oil?
Time to find a new mechanic.... What are the veteran diesel owners thoughts?...

Hey, the gas station I worked in during high school had those! I remember filling them from a bulk tank inside the service bays. Remember service bays?^^^^^^^
I love this. Is it detergent? (BTW, I'm old enough to remember oil for sale that was not only straight-weight, but non-detergent. And if I push my memory hard enough, I can remember the stations that had the oil racked up by the pumps in glass bottles with the tin funnels on top, because so many people had to throw in a quart or two every time they fueled up. People who long for the "good old days" are usually looking through a fairly narrow glass.
Bad analogy because lead paint is way better as far as holding up than what you get today. AS it was going out of style I bought all the white lead paint I could find for painting fences. Still looks great.Mentioned this to a co-worker this morning. His comment: "Lead paint used to be great, too."
Just to keep us off topic (the topic of this thread is silly, anyway), paint improvements are pretty recent. First paint job on my 19 year old house lasted 7 years. Second lasted another 7, and I was overdue for repainting both times. Had some trim rotting as a result. The current paint job (two years old) is some new age paint that seems to be lasting much better.That is not true, modern paint chemistry has taken GIANT steps in recent decades. The stuff you buy today is far superior than anything made during the lead paint era.
Air cooled VWs do better on straight 30. They always seemed to burn up the multi weight oils faster. Plus, the oil cooler bypass valves were designed for the heavier oil.Sounds like your mechanic is an idiot - sorry to say.
