Hi guys, been hammered to death I know, just wondering if theres any reason Castrol GTX wont do 6 month intervals.
I was running synthetic, but with decent sized sump in the Jeep, and roughly 9K miles a year, swapped to conventional. The Mazda still gets syn.
The owners manual allows 6 month/ 6K changes for normal driving. I do a decent highway run every day, with about %30 city driving. Not much idling. I usually cover 4.5K in 6 months.
Would this be fine?.
thanks.
