Engine oil RED LINE or Motorcraft

I personally use Red-Line products, and it's the absolute BEST products out there. Their 2 Stroke racing no smoke oil is OUTSTANDING and 2nd to none.

switch to 5w20 as according to fords bulletin for oil, i been using motorcraft synthetic blend for 26 yrs

Redline and royal purple filter for my 17 ram sport 5.7. 60kish on it now.

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.

'17 f150 5.0l with 150k running 5w-20 motorcraft. Not a single problem and this was used to haul a 12' steel enclosed trailer loaded from day 1 and the wind blows a LOT here. Doesnt use a drop of oil.

I've run Redline in my '01 Golf & my '10 Touareg TDI's for Hundreds of thousands of miles. No worries!

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.

I use Redline but it’s about the same price if not moreso.

I run motorcraft in my mustang and have zero complaints.

So when i changed the car to 10w40 redline I noticed that the car began to knock around 3-4k which it didn't do before and now it seems to slowly get worse.
