Oil advice and recommendations here

[mikeyp]

i'm just about to change my oil and filter and have had conflicting "advice" as to weather to use an engine flush before i drain the old oil.
should i be using an engine flush at all? are there good and bad ones?

also, are additives like slick 50 worth using with a decent fully synth oil?

i'm running a lightly modded R with only road/fast road use.

and when i do my winter service what oil should i be using in both the boxes and the engine for a full winter (5 months) of driving in the snow and ice in the alps?
the daytime temps are below freezing and the nighttime temps can be as low as -30*c

Also why do Different oils show me Different Oil Pressure?

There is no need to flush the engine and flushing can be harmful. What can happen is the flush can loosen harmless deposits in the engine, but then not remove them. Your new oil goes in and after it gets warm and is flowing nicely, the bits which are loosened come off into the oil, so you end up with hard bits floating around in your oil - the last thing you want. If you really want to flush the oil system, the best thing you can do is drain out the oil that is in there, put in some mineral oil and run the car for a couple of days. After running it, drain out the mineral oil and put in the correct oil.

Don't touch oil additives (except limited slip friction modifiers, but then only if needed). Good quality modern oils contain everything they need, so adding something knocked up to make easy money isn't a good plan. Have a look at the link below

Some oils are thicker than others, some can be affected more by temperature, that will affect the pressure.

With it getting that cold in the winter, you could use a 0w-40 or 5w-40 oil, or possibly invest in a sump warmer.

Hi

Go for a 10w-50 if it's driven hard and these are the ones that we stock.

http://www.opieoils.co.uk/c-659-10w-50.aspx

Both are really good oils, absolute top of the range ones, so go with any brand preference you have.

A 10w-40 is a better choice for normal use

http://www.opieoils.co.uk/c-657-10w-40.aspx

The best ones are the Gulf Competition, Motul 300V, Redline and Millers CFS. As a cheaper alternative the Fuchs XTR, Motul 6100 and Millers XSS are good choices.

Cheers

[dave_gtir]

how much oil do the pulsars hold exactly?

 

[danr]

3.7L with new filter

 

[Spikey]

Do you know about Transmission Fluids?
Can the Honda MTF be used on our Nissan Pulsar?
Nissan Recommend 75/90
just Hondas mtf would be thinner

 

[oilman]

I'd go for a 75w-90 rather than the Honda MTF

Hello mate I'm going to be doing a full service on my car soon changing all the oils but I haven't owned my pulsar for very long so was just gunna look for some advice on what oils to use really.

The car is a 1993 pulsar gtir, it has around 99600 miles on it with a full exhaust system and front mount intercooler running around 1bar. The top end seems a little tappy as well so if tree is any oil I could use to quieten it down a little bit that would be great also would like to know please what oils to use in my diff, transfer box and gearbox.

Your help will be greatly appreciated

ATF in the transfer box? That's a new one on me.

ATF in the transfer box? That's a new one on me.

I think it's technically for the viscous coupling, but as that's a sealed unit it doesn't get changed unless you've got the whole lot in bits. I'm pretty sure I put 75w90 in mine.

For some reason that's what's in the Opie Oils database, and someone always comments/corrects it.

 

[Animaldaz]

But the transfer holds the front diff which is open, centre is in the gearbox. Stock set up I mean.

 

[PobodY]

Er.... good point, that's something I always get wrong. - I still think the ATF is to go in the centre diff if you ever take it apart.

I have used these products for 40 years in a variety of cars and currently in my GTI-R for the past 10 years.

If you follow these guidelines then you cannot go wrong.

Gearbox / Transfer Case / Differentials Castrol Syntrax 75W-90
Brake/Clutch Castrol Response Super DOT-4

Have also heard this.

A lot of people get confused with Automatic transmissions and put ATF in Manual gearboxes and then wonder why the gearbox breaks.

 

[oilman]

ATFs go in a lot of manual gearboxes, things like the Getrag boxes used in Skyline R34 GTRs, many BMWs, some Supras, some Mercs, etc etc etc, and they work absolutely fine.

Our data does say it needs an ATF in the transfer box and to be honest, before I posted that up, I was a little unsure about it. As I couldn't 100% remember, I went with the standard data.

 

[red reading]

ATF fluid is probley used if you have a lsd front diff, you can also use 75w/90w with friction modifiers. i would'nt use atf if not needed and definatley not in our gearboxes. getrag boxes have internal oil pumps so the reason they use atf will be the anti foaming properties to stop the pump pushing air.
