I have hopefully sold the GTA anyway but I just didnt want to screw the car for the next owner if I could possibly help it!
I am now on the look out for a nice sportswagon JTD, fancy a change rick?!!
err... i think its very much advisable if you first confirm whether the Selenia 10w-60 is 100% FULLY SYNTHETIC or SEMI-SYN... cos i believe the CASTROL 10w-60 is FULLY SYNTHETIC???
One of the reasons im using AGIP 10W-60 is bcos it is 100% FULLY SYNTHETIC while the selenia 10w-60 isnt... so its best you confirm this point before mixing them up.
i do believ there are issues/problems regarding long term usage of mineral oils and a full switch to 100% synthetics... read somewher that doing so will likely cause the engine to conk out on u...
so my advice is pls check...
