Hello well i bought some castrol gtx for the oil change, but i did not realise it was 'mineral'. would it be okay to use it? 10-40w. and i do change the oil every 6 months ish.
Reason i bought it because i thought it was a great deal for 5 litres only 10 pound. and it says its good for stop start driving and high temperatures.
car came with no history so no idea what sludge is in the engine atm but theres mayo appearing and i want to change it for fresh start. theres a selenia sticker under the bonnet but i dought thats whats in there....
Also its got an oil leak (the undertray is covered in oil) so im not spending 45 quid on castrol edge or something lol.
Oil is really confusing for me... i paid 18 quid for semi sythetic eurolite and carlube before that 10-40w for my old car but that was an old engine type. (94 polo)
thanks
