injector oil

[nrpd diesel]

has anyone ever changed the oil on the top of the motor. it's about three quarts. the oil is used for the injectors.

no need to change the HPOP res...but it should be about 1/2 inch from the top....hth

[storkerlovr]

no, most things that guy on powestrokehelp.com says are incorrect.

that oil has not yet been circulated yet, it will mix in to the new 15 qts that you add in the oil change.

their is no reason at all to "change" this oil at all. unless you want to pull the whole HEUI system apart; pump, oil lines, pickup tube, both heads, all injectors.

if this were common procedure the you would rear apart every engine and spray it down with brake cleaner. but it isnt.

just change the oil tht drains out of the oil pan.........on the bottom of the engine

i suck out the res because i have an oil extractor, but its not something you have to do at all. the hpo system is not closed, it uses crankcase oil and is circulated through the lpo pump, to the res, to the hpop, to the oil rails, through and out the injectors under the valve covers and back down to the oil pan, where it starts sall over again. bill hewitt is a nutjob on most things, including his prolong injector treatment.

They're right. The HEUI system is supplied by the LPOP. It's all the same oil.

would anyone recommend an oil additive when changing oil or just stay with the shell rotela T?

[jesilvas]

No oil additives because of the way the HEUI system works. Read: How HEUI works and best to convert
Rev-x is the only thing that has really been shown to do good.

I read on another forum about an additive called Hot Shot Secret ,of course I had to find their website .They claim it cleans the oil side of the injectors,less noise,and better performance
it was fairly interesting and kinda peaked my interest.Has anybody had any experience or heard of them ?

[jesilvas]

Lucas claims stuff, K&N claims stuff, etc. I know what you're saying though.
There's been some threads on Hot Shot also.

^^^ they all claim to help, few actually do. IMHO if you are using a good name brand oil (rotella, delo, delvac, premium blue..etc) you should have no need for any additives. This aren't the oils of the 1980s, so long as you follow a regular maintainence interval you shouldn't have sludge built up in your engine.

Good link on Lucas:

What about Additives?
