> but the commerical says its good :rofl

my dumb ass fell for the marketing, and a lot of the tests and reviews i’ve seen online say it is good, but as previously mentioned by slowmarro i’ve read that it breaks down quickly under high heat…so my next oil change will be with bg oil…i may also switch to bg gear oil for the diffs but im not sure if that would be ok (jeep says use 75w140 for the diffs and bg is 75w90), the jeep hass been on moa since i bought it (49000 miles) so im not too worried as i’ve only done 1 rp oil change so far, and im at 96000 miles now and it runs like the day i bought it.
