yeah i read alot about sludge but from spending all day at work reading up on it it's like one person has said it and the rest have followed ..?
who has actually used it and had any problems? what is in magnatec that isn't in other semi synth oils that can be pinpoint to creating sludge,, i just dont follow..!
in saying that after reading up im more inclined to not swap the 10w60 castrol edge sport in both my rb25 and rb26 to the magnatec i just figured visco is about right and at $25 a bottle (normally $40 i must say) it seems an option
i have been using magnatec in:
2007 corolla from 30k to 100k! changed every 10, comes out relative clean for car of its age, no sludge.
1997 prelude for 25k - the engine has chronic piston slap but hasn't got any worse since using this oil - no sludge
1992 bmw e30 - maybe done 1000kms since we bought the car but can't see any problems yet..
i'm about to put it in old mans hiace with 220kms on the clock.. he's also thinking of switching from penrite and buying a dozen bottles of magnatec!
if its truly rubbish then yeah ill give it a miss but seems its all heresay
