Turbo Blankets / Exhaust Wrap

One of the major advantages of synthetic oil is resistance to coking, but this is only true of the synthetics. Mineral oil will coke and shutting a turbo down hot will do this, I'm concerned about the heat soaking that occurs after shut down....and the heat build up occurring in a hot turbo on a really hot day.... ambient temperatures will cause something hot to reach hotter operating temps as anyone who has ever overheated an engine on a hot day can attest to....

 

I see you listen to Kevin Rutherford. He calls conventional oil mineral oil too.

 

No, I don't listen to him. I call it mineral oil because it's the term used to distinguish it from synthetic.

 

Is there a reason not to listen to Kevin Rutherford? Not that I care for the guy but I think he doesn have quite a lot of good knowledge in the numbers of trucking and more informative than the guys in the truckstop or on the cb.

 

My little windmill fell off the shaft of 7cz,I was 2 hr into a 7 hr bobtail. I went to the house going soft on the pedel. Then ordered one from kurt the next moring that was a little bigger and better
and had it in 24hrs from order time.

 

Myth #7, you don't have to spool down, or allow to cool down...lol...

This idea was heavily promulgated and fleet managers were carefully watching idle times at a company we used to work for....

They had many, many premature turbo failures as a result of their anti-idle zealotry...

Something like 40% of the fleet experienced turbo failures within 100k miles....

They revised the policy, decided to allow for 10 minute idle period before shutdown...lol.... gets a little expensive after awhile, replacing turbos...

Me? I idle my truck for 10 min before shutting it down. 500k on the turbo, must be doing something right.

I've thought about a turbo blanket, haven't bought one yet....still thinking it over...

 

Well, I hardly ever do cool down for the turbo. I have not lost a turbo because of that.... ever, in over 5 million miles. Sure that is spread out over a few trucks, but one I took to 1.4 mil and it still had the original turbo. I used a turbo blanket on my last one and my present one, and it now has over 200,000 on the original turbo and nary a problem. Generally, the turbo and EGT's have cooled to a safe level just by coasting in on the off ramp and then trying to find a place to park. To be fair, there are instances where it is called for. For instance pouring on the coal to climb a hill and then immediately pulling over and stopping at a pull off. Sure, the pyro still shows some temp there, and I will just idle enough to drop the pyro. Usually no more than a minute or two. But most cases, it is not necessary to do the cool down thing. Let your pyro be your guide. It will not hurt anything to do the cool down thing, but most times, it is totally unnecessary.

 

Ya, I need to hear that also

 

Yup. 3 trucks. At least a million miles. And nary a turbo issue. And I don't let the turbo cool down

Oh wait. I had to replace one actuator on one of the ISXs.

I've been thinking about the blanket too. But I have a DD15 and no clue what blanket to buy.

 

I got the PTP blanket today and looks very well made. In rhe morning I have the PB manifold going on with the bigger turbo 171702 the PTP blanket and the wrap. I've been tracking my MPGs on fuel gauges since sept. I'm at 7.2 for last 90 days. Can't wait for the MPGs to go up even more.
