I am gonna get the 45,000 service on my TJ VR-X auto done soon, but I will buy the fluids

The service is only to change

. brake fluid
. coolant
. engine oil

a) What are the Mitsu recommendations?
b) what would/do you use in your TE-TJ 3.5 V6?

Thanks!

My Haynes manual recommends:

Coolant: 50% Ethylene-glycol based antifreeze and 50% demineralised water.
Brake fluid: DOT 4 brake fluid.
Engine oil: no recommendation. Personally I use Castrol GTX3 and find it does the job well. It's a 15W40 weight, however you may want to consider a 10W40 as well.

If your getting your car serviced why not let them use their own stuff? I don't think there is anything special about the Magna's requirements and most workshops supply quality fluids.

The only thing you really need to be careful about is the transmission fluid - make sure they use Mitsubishi's own.

Motul DOT5.1 brake fluid is the sh1t... Only $15/500ml so much cheaper than the EBC DOT 5.1 which is around $30/500ml. Will need up to a full litre to fully flush out the system including the ABS actuator.

That's pretty expensive brake fluid even for the Motul.

Is there a compelling reason to use DOT 5.1 vs. DOT 4 in Magnas?

^^^ Much higher boiling point in DOT5.1 fluid.

Yes but is there really any benefit to that in a Magna with standard brakes?

Hey all,

Cld anyone answer the question please??

i let mitsu change all the fluids with their inhouse - diamond stuff EXCEPT engine oil...

which i use mutol 4100 as a replacement...

other recommended engine oils include:

Penrite HPR10
Mobil1
magnatec

Mitsu dealers use Castrol Magnatec... ain't putting MAGNAtec into my Verada. :badgrin:

My young V6 loves Motul 4100 10W40, I flush it every 5000km.
BYO the Motul when the car goes to the dealer's for servicing.

Older engines could do with a thicker 15W40; lots of good rap for HPR10 & HPR15 Penrite.

Am currently experimenting with Valvoline XLD Premium 20W50 on my older V6,
seems to be working ok. (Have a tonne of the stuff stocked up from my TN days.)
Fuel consumption could have gone up a little bit but hard to say, might be driver error.


Coolant... just get something that is compatible with alloy engines. Nulon usually good.

Don't really need glycol antifreeze unless you're going to the snow,
water + rust inhibitor is more efficient at transferring heat if it snot subzero.


Brake fluid, I go for Dot 4 but in the Heavy Duty "clear/yellow" formula.
Green & red are usually normal duty stuff.

There is NO benefit in using Dot 5.1, only a racecar will need higher temps.
Save your money and use Dot 4, then spend that $$ by changing your fluid more often.
Having fresh Dot 4 is much better than keeping stale Dot 5.1 in your system.

bodily fluids possibly? :roll: god im bored...

i reckon shell oil pritty darn good no ones really mentioned shell oils on this formus

Mitsu dealers use Castrol Magnatec... ain't putting MAGNAtec into my Verada. :badgrin:

The dealer where i go use Castrol FMX Semi-Synth 15-40. There's also a Magnatec FMX 10-30 i don't think they use the latter. plus they only come in 200 or 240l drums

i think this really depends on the age of the car when it comes to engine oil.
mines done almost 200k kms, and so i use 15W50.

The newer ones seem to do ok on 10W40s and 5W40s.

I use Diamond Guard Mitsu fluids except for oil where I use Shell eco 10 10W-30.

Note that not using glycol in the radiator (at least 3%) is a risk (a pretty big one IMHO) - can you ever be absolutely sure you won't be anywhere near a frost for the following two years??? Here in Canberra I use a 50% mix...

If you're so worried about your radiator contents freezing up,
have you thought about the windscreen washer reservoir? :P

Yep... but washer detergent prevents that :)

Coldest nights here are about -7°C (and some towns in New England scored -9°C last week!)
