Id use what it says in the manual mate. I thought 10-40 oil was for older cars as it isnt as synthetic, 15-40w is synthetic so better for your engine.
hehe, what !.....thats pretty wrong mate !
10W-40 can be had in fully synthetic, and semi synthetic, as can 15W-40 probably, though ive never seen a fully synthetic 15W-40, only semi
SHORTY, i assume what you have is Total Quartz 7000 10W-40......green trim on the label ?........and what you were looking at was Total Quartz 9000 5W-40.......pink trim on the label
both will be fine, however personally id go for the Quartz 9000, for a start its fully synthetic, which the 7000 isnt.........
not many people do a 5W-50 as its a very wide temp range so is packed with additives = bad...........Valvoline do it......
most semis........or fully synth oils will be fine........depends if you want the best or not.........
