my previous quick lube went from castrol gtx with a champs lab filter to gulf motor oil with a champs lab filter and it's 25.95 plus tax for an oil change, and after they made the switch and also because of overfilling/mistakes, I stopped going and began being a DIYer
regardless, how is gulf motor oil, and is it worse than gtx (less additives) and is their syntheitc oil also weak? another quick lube, victory lane oil change, (multiple locations, one uses castrol, one uses formula shell and amsoil, one uses shell in addition to gulf synthetic for 40 dollars and mobil 1) and the mobil 1 oil change is 75 whereas their gulf synthetic is only 40, which makes me suspect it's not high quality and is similar to meijer brand synthetic or oreilly's brand oil which i heard had a weak additive package
is gulf motor oil similar to peak motor oil or is is like chevron supreme and isn't as marketed as castrol or pennzoil but is, in reality, a really good conventional and or syntheitc?
i've heard the conventional chevron supreme is good but i heard they also make a synthetic
is the chevron supreme synthetic any good or is mobil 1, amsoil, castrol, pennzoil better for synthetic and i should only use chevron for dino and leave synthetic to the "classic" ones which are sold everywhere and hodl more market share like mobil 1?
is gulf synthetic any good and how does it compare to chevron supreme or the "name brands" like mobil 1, amsoil, etc?
i was asking because i dind't know if i should DIY it with mobil 1 which i can get at walmart for 22.57 as it's been on sale + filter, or is it worthwhile to consider a synthetic gulf oiil change at a quick lube place that uses a decent mighty filter, i heard mightys were purolators and that champs lab ones were bad and were ecores like ac delco, supertech, stp (i mean similar to fram but not as bad as fram orange can, but neverhtless cheap, but still better than fram)
