Quick question, mobile1 being 5w-50, isn't that going to be 2 thick when warmed up? Thicker = slower revs?

it should be fine...alot of people use it on the forums from what i know..there is also i diff type of mobile 1...0-40w rating hard to get for only workshops from what i have heard. Would be nice to get some..

[Brody]

hhmmmm...then would something like castol -R be better as its rated at 5w-30?

I just took out all the black shit that was in there, topped it up with fresh mobile1, took it for a quick spin, didn't really noticed a difference....other times ive had it flushed i have

When u do an oil change, do u have to change the filter everytime?

I use a mechanical oil pressure gauge, if all is set up ok there is no rear problem, but unsure of legalities.

Brody, why put $50 of oil in and not spend the extra $8 on a filter just to be sure. Otherwise you still have all the old oil and dirt in the filter with the new stuff flowing through it.

mobil dont cope really well in temp department.

Thats contrary to an article i have (had?) that rated the Mobil1 as having the best high temp stability of all the oils tested (approx 8 oils from memory)

I have used Mobil 1 on this basis and with my engine having done 155,000kms, 3,000 of which have been at prolonged full throttle on circuits... it seems to have peformed well at high temps.

This is a good read, as im looking for a different oil after 6 years of using Mobil1, its getting too expensive.

Your thoughts on using say a 10-50w etc for an engine with higher kms say 155,000kms?

I found little difference between the 2 on the street. Shell was probably better because of it's pricing even temps was only a tad higher, but of no concern.

But on the circuit I like the Mobil 1. Shell, the temp rose to rapidly and went well above 130 degrees. Mobil sat at 115 degrees.

by any chance can anyone get 0w-40w Mobile 1 in Melbourne??

Clinton - how did you hook it up? Where do you tap the line into ??

You can get mechanical oil pressure gauges but they can't be mounted in the cabin. Hence people putting them on the bonnet.

Electrical oil pressure gauges which use a sender are fine for cabin mounting, but are more exxy and may (as someone said) have a reduced range. However as long as it covers the expected operating point of your oil around the middle of the gauge it'll be fine. I really don't think oil temperature should vary by 140 degrees!! (if base temp is 40C then 180C is your top temp.. fairly hot oil!)

[Clint32]

Jay i fitted i remote oil filter and cooler so the filter mount had a spare fitting that i used, otherwise im pretty sure you are able to buy a plate that goes where the filter is and the filter screws to that. Remote filter is not hard to set up either and makes changing the oil very simple.

[Guest RedLineGTR]

sounds about right...gotta find out about the plates..

[Jay95R33]

Ahh cool - thanks Clinton.

Looks like I'm leaning towards the exhaust temp gauge then.

ahh

well i got a 93 gtst

and i just put helix ultra 5-40 in

and im having the pressure problems aswell

if it doesnt sit above a qtr i get very cautious

but yeah it sbeen in for 2 weeks now

and sits VERY low at times

around 5-6 at startup till its warm

maybe because it runs so hot it flows free'r?

who knows

ill dump it after 2 thou
