dunno what oil only just bought her :wink:
almost 60k. 1995
also does your gauge when hot engine ever go to the bottom when on tickover?

what the pressure? not that ive noticed no mate
wot does it say in your service book? the oil used i mean.. if not phone up the garage
how mutch it cost you
mine were still warm from earlier but idling at 800rpm it was at 1 dead level, give it a rev n it climes!

in the book ,
15W/40 - 15W/50 its says for outside temperatures of -15 to +20 celsius

how mutch it cost you
how much the car cost? ya mean?
i mean when engine is red hot and on a hot day have a look then..
mine is on just over 1 but when been out on hot day on motorway and runing around i have seen it 1 notch up from bottom of gauge
my last one did this but saying that it was on 3 when stone cold driving around :cry:
and on 2 on tickover when stone cold
how much the car cost? ya mean?
yea

no idea mate only just got it
good buy for milage..
you got green coolant yet? :wink:
wot a twat to get that bottom hose off :lol:
Justin..
12-09-2005, 21:46
nah its still red :? thinkin about gettin a bbt low temp switch thing and samco hoses just for the looks so wait till then
in the book ,
15W/40 - 15W/50 its says for outside temperatures of -15 to +20 celsius
10/40 the top one
no does not even tell you in the haynes manual about pressure reading when cold only at running temp pressure

what diference does it make?
try these for your coolant.. i think they sell them hoses

whats the difference between 10W/40 compared to 15W/40?
15/40w the 15 is when car is cold ( the thickness of oil ) the 40 is when the car is hot
so 10/40w is better when cold gets around engine faster
alot of the members on here use 5/40w
but allways used 10/40w in the one i have now because the last garage who serviced it used this + the gausge reads bang on when at optimal running temp..
was thinking of going to 5/40w but i mit get a differant reading :roll:

oh rite
mine reads 0 bar at idle when hot but the oil light doesnt come on and the engine is quiet too so i'm thinkng a new sender will sort it out
i never get the oil light coming one
wot oil do you use? :roll:
also 0w-40 you may find a little thin when cold not for that engine
ok for a 5gturbo

When its at full temp at idle mine sits at 1 notch above 0. Don't think theres any problems, theres no excess wear I can see and its still getting pumped onto the cams.
See ya
Matt
All 3 of my pod guages dont work full stop :cry: any suggestions?

Take em out and check the wiring. Probably an earth wire fell off or something simple.
See ya

when warm, idle pressure should be 0.2 bar hence it doesn't show on gauge. Nothing wrong with the gauge. When warm, it should read about 3 at 3000 revs
Why does the gauge read high when driving a cold engine? Oil's thinner when it's cold!
oil is thick when cold hence the grades 5/40 10/40 15/40 first number is the cold thickness
gauge is bang on when warm.. is right when cold gauge right up when cold
gauge will go lower if i put a 5/40 in engine
I'm sure I read that engine oil's make-up is such that it got thicker when it was warm. That never made sense to me though. What does 'W' in 10W/40 mean?
'W' in 10W/40 mean?
Lubricants that are able to maintain their performance in high and low temperatures are called multigrade. They are defined by two numbers. The first (followed by a W) indicates the lubricant’s viscosity under lower temperatures. The second and higher number indicates the lubricant’s viscosity under greater temperatures. A multigrade lubricant minimises viscosity differences under temperature variations.
