Hi Guys,

I am overhauling all of my fluids and I thought I would get your opinions on the brands and weights you recommend. My car is a 2004 Maserati Coupe GT 6 Speed Manual Shift with 26,500 Miles.

The engine oil is the most grey area. I hear that a 15W 50 Mobil One is a great oil for the 4.2L once it has more than 20,000 miles on it but now I am hearing it is too heavy of a weight for cooler mornings (like we get in Calgary Alberta Canada even in the Spring, Summer, and Fall). I could just stick with the recommended 5W 40 Mobil One Synthetic that it comes with but I hear Ferrari owners are using 10W 60 Mobil One lately. What do you think?

The Transmission/ Differential Fluid is pretty straight forward; 75W 90 Synthetic with a GL rating of 4 to 5. The brand as per Maserati should be Shell. Any recommendations?

Finally I come to the issue of the coolant. This is something that is more critical to me because I have seen different brands and grades rust out the internals of an engine! The recommended brand according to Maserati is a Glyco Shell with a mix of 50/50 and a tolerance of -18C (24F). Do I have to stay with this or is there something better out there? Also what mix would you say is best?

Thank you in advance for any suggestions!

Cheers,

Maz :autofahrer:
 
MAZ, here in florida im using 0w 40 mobile 1 cuz i couldnt find 5w40, but completely different temps between here and where ur at. some dealers use quaker state. as far as coolant goes, if i remember correctly my dealer uses napa brand. the most important with coolant is to buy phosphate free
 
Use Redline brand engine and gearbox oils, I recommend sticking with the OEM oil weights of 5w40 and 75w90 as well. You DO NOT want to use GL 4 OR 5, they're very different oils...you need to use the GL rating recommended by the manufacturer, in your case the GL5 which would be the Redline 75w90NS GL5.

For coolant i like to go to my local Honda, Audi or BMW dealer. They all have good quality coolant designed for all aluminum engines and are more reasonably priced than anythign from the Maser dealer.
