Question about synthetic and diesels

[Greg_B]

It would be interesting to see what oil pressure readings other owners are getting.Cheers,Nick

Stock gauge readings mean nothing............

I have put mechanical pressure gauges on engines in which the stock gauge did not read at hot idle, and gotten readings of 35psi hot idle.

I have put mechancial pressure gauges on engines in which the stock guage read 1/4 at hot idle, and gotten readings og 35psi hot idle.

Put a gauge on it if you really need to know.

Typically speaking I am around the 1/4 mark. Sometimes above and sometimes below. Depends on air temp, engine temp and RPM.

When the engine is hot, and the air is warm, and I am idling it is the lowest it goes. Around 1/8 (ar a little below) on the needle. I was at first really worried about this. But now I am not so worried since my oil is the same as the 15x40 when warm.

Also my BEB were done, so I know its not that (cause the low pressure)
Also my oil light has never come one. So that make me feel better.

i have seen ultra low HDJs with very low readings and i have seen high km units with a constant reading at half way...
as Greg says you really need to install a mech gauge to know for sure...

Here is a picture of the Amsoil bypass filter in my LWB Samurai.

you keep a nice engine compartment I see adel clamps and nicely routed wires.

Congrates on a nice job!

This is a interesting issue . not about kind oil you use .. the real point is the low press in 1HD-T.

At normal operative temp and idle my reading is to low .. les than 1/4. Worried .. yes little. I'm using right now Castrol Viscus Max 20W-50 but plan in my next oil change run Castrol GTX 20W-60.

But I thought is only hiding other engine issue .. maybe BEB or other king or issue.

Why are you running such thick oil for a diesel?

Low oil pressure is a sign your big end bearings are stuffed.

Amsoil is for sure the best oil on earth, but I seriously need to look into these by pass filters, could anyone tell me how hard it is and how you install one? Can I buy a kit that includes everything? If so is there a CDN source.

Which Amsoil one fits on a 3B, if it just screws right on I think i'm sold.

I use Canadian tire brand Diesel oil, 10:30 winter - 15:40 summer, fram filter, gunk engine cleaner every other oil change, oil change at 4000 kms.

Oil pressure is just above low at normal idle engine operating temperture.

[Eric Winkworth]

what is low?

 

[Gold Boy]

what is low?

Low as in bj74 oil presure gauge

Don't use a fram filter.

Here in Panamá right now outside of my office you get 32 - 34ºC and a lots of traffic .. with 80 - 90% relative humidity.

maybe ..

I agree, Fram filters suck bad. Delco or K&N HP3001. The nicet thing on the K&N is the 1" socket fitting on the top which has a hole through it to wire it in place, for those who are paraniod of loose oil filters.

Wow, sounds like MD in the summer
