efseiler Posted June 13, 2014 Share Posted June 13, 2014 Is there any big difference between the green-colored coolant and the other ones? My Dad bought a jug of yellow (Shell, I think) stuff and I was wondering if it's ok to use... Thanks, --Damien Quote Link to comment Share on other sites More sharing options...
TallonX Posted June 14, 2014 Share Posted June 14, 2014 Green - normal Orange - dexcool Gold - universal Never mix green and orange, gold is good for both colors Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted June 14, 2014 Share Posted June 14, 2014 There are many differences in coolants, even if they're the same color. Kinda have to look at the label pretty carefully to figure out what's actually in the jug. Subarus are pretty picky about coolant. Using the wrong kind can cause corrosion and high amounts of silicate dropout which can clog the radiator and heater core. Peak Brand is supposedly safe to use. Th green stuff you can use but you have to remember to change it every two years. Quote Link to comment Share on other sites More sharing options...
efseiler Posted June 14, 2014 Author Share Posted June 14, 2014 Sez it's ethylene glycol based... Well...what do you guys think of this? Orange: An ExtendedLife, single-phase, ethylene glycol based antifreeze based on anextended life carboxylate inhibitor system suitable for use in all typesof automotive engines. Examples:ShellZone Dexcool Concentrate and Ready to Fill (50/50 Pre-Mixed),Pennzoil Dex-Cool Extended Life concentrate and Ready to Fill (50/50Pre-Mixed).

efseiler Posted June 14, 2014 Author Share Posted June 14, 2014 Oh I get it...you just can't mix them... Quote Link to comment Share on other sites More sharing options...
efseiler Posted June 14, 2014 Author Share Posted June 14, 2014 Apparently so-called 'Japanese green' is a deeper green and contains no silicates and just phosphates. It seems like that's what's in there now...or maybe it's just dirty from additives or wear.... Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted June 14, 2014 Share Posted June 14, 2014 (edited) I've used many different Coolants with Different Colours all long these years, and in my own humble opinion, the only one that provides a noticeable but slightly "Lower Temps" Results in overheating cars, is the Blue; Shellzone Blue. ~► http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1844910 Kind Regards.
