Hey guys, im kinda new here and ive been reading around your forum trying find what oil is best for the GPX, but i seem to be reading a lot of different things. My sister has a 95 GPX and she wants my to dump the oil and coolant etc. Now i dont know a great deal about FTO's as im a supra driver myself, but what oil/s would you recommend and what weight? I was thinking about using Mobil 1 with a low weight like 5w any comments??? Also i wanna get a stock Mitsubishi oil filter and sump washer are there any import friendly mitsubishi dealers in south east melbourne?

Whoops nearly foregot what spark plugs, spark leads and coolant do you guys recomend?

Thanx

PS perhaps someone could run a poll as to what brand or weight oil people run

then we would all know how many people use what oil.

groove,

I use Castrol Formula R Synthetic 5W-30, and I am happy with it. Used to use the Magnatec stuff, however, there is a big difference between two oils. I will stick with Formula R series.

Nulon Long Life Concentrated Coolant is my favorite collant.

You can get your oil filter from Repco/autobarn, they know what you need.

These topics have been covered many times recently and I recomment you to use the search funtion to get further details.

ok the following information is what I have been told by others... It took a long time for me to get a reasonable understanding as lots of people, including mechanics had told me different things.... but here goes..

the first figure 5 - means the viscosity of the oil at starting temperature. THe lower the figure, the thinner the oil is. (so 0 is thinner then, 5, 10, 15, 20 etc)

W = winter; applicable for winter use.

the second figure, e.g. 30 is the viscocity of the oil at running temperature (once the engine is warm). so a 30 oil would be thinner then a 40 and a 40 thinner then a 50.

Because the FTO engine is a free reving engine and because most engine damage happens at cold start I was sugggested to use 5w-30. Porsche etc use 0w-40 or 5w-40. Castrol or mobile 1 seem to be the most popular.

An oil like 15w-50 etc is normally used to protect against engine wear, and older cars. i have heard a lot of different opinions on when to use this. one mecahnic told me this was a better all round oil and would protect my engine against wear and tear, someone else said the damage was done at cold start and a thicker oil would jsut put more pressure on my seals etc.... so it depends who you ask. The one who recommened 5w-30 said he only EVER uses this grade of oil.

Ford/holden etc all recommend 5w-30 in their manuals from 99 or something onwards.

I have also been told the first figure being lower (e.g. 5 vs 15) will protect more against cold winter mornings, and the second figure being higher (50 vs 30) will protect more against hot/humid weather....

you could therefore go for a 5w - 40 or something, which is thin on cold starts, still reasonably thin once the engine is running at operating temperature but still protects it against hotter weather... it depends a little where you live...

I hope that is correct information, and makes sense to people reading it.. correct me if i am wrong
