Engine oil RED LINE or OEM Subaru

RED LINE Engine oil

I always used redline 5w50 on my S65 runs very well and redline has a great reputation of quality oil especially for its high performance cars. Takes less time to warm up too in low temperature climates.

Pros: runs very well, quality oil
Cons: takes less time to warm
Vehicle: BMW

2004 Dodge Ram 1500 5.7 Hemi 255,000 miles Redline 5w30 full synthetic Wix Filter Lubegard Biotech with each oil change....... 5,000 mile intervals. Had a hemi tick when i purchased used in 2007 {off lease} with 32,000 miles on it. The Redline and lubegard have a hefty amount of moly in them which helps keep the insides slick and hemi tick at bay.

Pros: keeps hemi tick at bay
Cons: hemi tick initially present
Vehicle: Dodge RAM
Mileage: 255000 km

Oil being dark is a good indicator that you have to do an oil change. However, you shouldn't wait until it changes color to do it. Clear oil doesn't necessarily mean you can keep going.

Pros: regular oil changes
Cons: sludge build up

OEM Subaru Engine oil

It is well established that boxer engines want their oil changed and I do not think for a second that a visual inspection is valid for determining if it is time. Highly, **highly** recommend you change the oil per the manual without hesitation and regardless of what it looks like.

Pros: recommend oil change
Cons: visual inspection invalid

0w20 provides your engine with more wear protection .

There is minimal difference between 0w16 and 0w20, with 0w20 provided marginally better wear protection and 0w16 providing slightly better fuel efficiency since it's slightly thinner and provides less internal resistance.

Pros: better wear protection
Cons: less fuel efficiency

Engine was noisier with the mix vs. the previously used redline 5w40. Iron levels are up at 6.3 ppm/1000 miles Oil usage increased by 1/2 quart over the redline 5w40 TBN/TAN levels are worse than 5w40 at comparable mileage

Cons: Engine was noisier, iron levels up
Mileage: 5000 km
