Plugs are very good.
I think the Castrol Magnatec is semi synthetic but the Mobil 1 is fully synthetic so probably better off with the Mobil, check it with Opie oils you will get all the info you need for you car there.

kaz_r555

ah ok, if the castrol is fully synthetic then is it that better?

or the mobil 1?

ive been told magnatec in unsuitable in impreza engines due to carbonising at high temps in the turbo,stick with a fully synthetic mate as stable at high temps.

Fuchs Titan Pro S Fully synthetic, or Motul.

kaz_r555

whats everyones views on mobil 1 fully synthetic with everyday use?

kaz_r555

just spoke to opie, they recommend the 5w 40 titan golf competition oil, at a decent price. is 5w 40 good? or shall i go with 10w 40 mobil 1?

I use Fuchs Titan Pro S Fully synthetic 5-40w and it comes very highly recommended, but I have a 2006 STI not sure if yours would be different, have you checked what the hand book says?

chopperman

Me too

Mobile 1 is a very good oil. 10-40 is ok. I prefer the lighter 5-40 as i do short trips and the uk is a cold country. Ive read scoobs dont like 0-40 or 0-30 though.

for my daily driver classic, ive always used Mobil 1 15w50 Motorsport. for a classic i wouldnt be putting anything lower than a 10w...in it

I used Mobil 1 in my scoobs for years with no problems, although I now use Fuchs pro s. I,d recommend Mobil 1 over the Magnatec. Steve.

I think the classics prefer a slightly more weighted oil than a newage, especially if they have some mileage on them.

kaz_r555

opie have told me that the '5w' means the oil circulates faster when the engine is cold over the '10w'. so the '40' is when the engine is at high temperature..

i think ill go for 10w 40 seems safer. mobil 1!

chopperman

Exactly right hence my comment about using a 5-40 because i do short trips and the uk is cold

i use 10/40 magnatec in my classic,no issues over the last 5 yrs of daily driving/spirited rides etc

Gary WRX

Same as me I use a 5w due to doing short trips

kaz_r555

So all in all 5w is ok for the classic engine? Why do people not like the magnatec?

Just want the right oil for my classic so it doesnt go bang!! Lol

Gambit

iTrader: (6)

no i wouldnt put 5w anywhere near a classic

10/40 for classics folks

just be mindfull a friend worked for a reputable oil manufacturer a few years back and the same oil was being put into Asda containers

All oil comes from the same place...........

chopperman

Yup it does. It all comes out the ground. The difference between mineral, semi, full synthetic ect is the additives but its the additives that look after our engines. Castrol mag is a good oil and i think would be fine in a classic. I to would go for a 10-40 in a classic or high mileage car. I doubt you would see any engine damage let alone one go bang provided you use one of the many quality oils on the market. Stay away from cheap ****e or recycled oil.

btiltman

Agree..... my MY99 always had Magnatec and I just passed 294,000km with no engine issues so far

I wouldn't put magnatec in my sub
If it was free ( millers or royal purple for me

Can I just add , it may be fine in a standard engine , as thr have been many past threads on oil in past & some guys have clocked big miles on the stuff
.... But it def wouldn't be on my or many others list for a built engine .

Magnatec may be fine in a standard engine or for non turbo but it is a very basic oil. It's not a proper synthetic and is inferior to brands like Millers, Fuch or Motul who have proper fully synthetic oils designed to cope with hard use and elevated power levels. There are lots of folk who have used it for years with no issues BUT as an engine oil it's not something I would use in my Impreza.
