I use 5w30, I used to use Schaeffer but it's too expensive now so I switched to Rotella.
Owner reviews for engine oil
Penziol platinum on my 23. change it every 5k and it’s still golden
Ik heb Castrol olie gekocht die synthetisch is. Ik heb geen expert maar voor mijn 23 jaar oude Ford Focus neem ik liever het zekere voor het onzekere.
Decided in the 5w-30 because the engine seems to run a bit smoother with the 30 weight
Originally switched to Amsoil for the Noack rating but stayed because it's just good stuff. I now run Amsoil products for all fluids in all vehicles.
Might I suggest Valvoline Restore and Protect. It is magic in a bottle and it's anti wear package is off the charts with oil analysis.
Been using Zic on two Hyundais (Tucson, Santa Fe), and ok yung performance niya. Maintained yung cars with fully synthetic, 10k/1 year intervals. Smooth pa rin manakbo ang engine until today.
I use Pennzoil "Ultra" Platinum for my 2010 with 5.4 Triton and it runs amazing. At one point I did try Royal Purple but my engine was actually noticeably noisier so I switched back.
Got a call this morning from him and he said that the gasket/seal for the oil filter housing where it connects to block is leaking oil.
On the Gen 2 Prius that have been several reports of Pennzoil Platinum full synthetic consuming oil much quicker, me included.
