Hi guys, my 2014 jeep wrangler JKU
0 to 12,000kms - factory fill
12,000kms to 24,000kms - synpower 5w30 DX1
24,000kms to 36,000kms - synpower 5w30 DX1
36,000kms to 48,000kms - synpower 5w30 FE
48,000kms to 60,000kms - synpower 5w30 FE
60,000kms to 72,000kms - synpower 5w30 FE
72,000kms to 85,000kms - synpower 5w30 FE (this report, 13,147 on the report should be kms, not hours. Also i believe the starting TBN should be 10 for the synpower FE but not certain in Australia)
re-filled with synpower 5w30 FE
Daily commute is 2 x 18km trips six times a week, with a highway run once every two weeks. Did a fair amount of low range work on this oil change, had the jeep idling for long periods quite a few times. I ran a quality injector cleaner twice, i don't know if that contributed to the fuel dilution.
I'm not worried about the copper since its normal for this engine and its oil cooler to shed a lot of copper.
With my driving style, I'm thinking stay with the synpower 5w30 FE and change it at 10,000kms?
Should i look at a A3B4 oil like Mobil 1 FS 0w30 for a stronger TBN and a higher SAPS? Im out of warranty.
Im glad i wasn't using a 5w20, that is for sure. Thanks
