2011 Hyundai Elantra
Quaker State Ultimate Durability 5W20 4.2qt.
2450 miles (my 1st oil change)
Lots of little metal bits in catch pan from factory fill. Factory fill is standard QS 5W20 and the car really seems to like the QSUD
2004 Dodge Stratus 2.7L V6
Out: 4.5qts Kendall GT-1 High Performance Syn-Blend 5w-30 w/ Liquid Titanium (GF-4) +.5qt MMO & Bosch Premium Filter
In: 5qts Castrol GTX Syn-Blend 5w-30 w/ TriShield (GF-5) & Pureolator Pureone Filter
Got all excited seeing GF-5 Rating and "20% more deposit fighting detergents" and at $21 for 5qts and pureone filter I couldn't pass it up! MMO cleared up a slight lifter tick in a pinch.
Out (with less than 500 miles ): 2:1 thin:thick blend of Kendall liqui-Ti synblend and Delo 15w40.
In: 5w30 Valvoline dino shop oil plus Valvoline synpower additive.
I forgot to take off an old outdated service sticker and the mechanic accidentally threw out my nice new oil for some valvoline. So now my 'roo is going to run with the thinner 5w30 for the summer. It had a nice 50% larger filter for the 3l H6 engines too (from the subaru svt or xt6?), that seemed to fit fine despite the shorter threads.
On the plus side though, my subie now does have a fresher manual transmission and brand new clutch!! So it should be good to go for the next 160k miles.
