Engine oil RED LINE or OEM FORD

I love red line, search for my UOAs... i've tried most of the top teir vw502 approved oils in the FSI (Motul xcess, motul specific, total energy), and they don't even come close to touching red line with regards to longevity / performance.

4 qts Redline 5w40, 1 qt Redline w40 Race Redline blows away the competition... Lumps of ZDDP and Moly with the Race oil mix, fuel dilution pretty much disappeared, and viscosity/flashpoint are well within reason.

I would stick with a tested oil like Red Line 5w-40 or GC, but that's me.

Sticking with a single weight is a better idea than mixology IMO..

I have been running redline 5W40 since 5k miles in my 08 GTI and I noticed an immediate improvement in turbo spool up. Others have noticed this improvement on other turbo cars as well.

I am planning on using redline 5W40 which is not on the vw approved list but has an awesome HTHS viscosity and I have used it in my boxster S with big improvements over M10w40.

I've been running Redline or Royal Purple 40wt

Using Redline racing 50W in a SCCA 1.6L production engine with an oil temp of about 210 to 215 degree (F) on a hot southeastern race weekend. Hot oil pressure is about 70 to 75 psi at WOT and about 30 psi after a session in the paddock prior to shut down.

For the past 5 seasons, I've been running 5w-30 Mobil 1 but recently switched to Red Line 30 Wt with no ill effects. Typical oil temps (racing on in the Mid-Atlantic area with temperatures and humidity in the 90s) are 250ish with 30-45 PSI hot oil pressure at full chat.

Mobil 1 0w-40 is approved by VW, Porsche, MB. If you don't mind the price, Redline 5w-40 is excellent for our 1.8T engines. From the oil analyses I've seen, Redline has shown a few \"Parts Per Million\" less in metal wear than Mobil 1 5w-30 or 0w-40. Redline has more Moly than most oils. But for me, a few PPM is insignificant over 7k-8k miles. I still use Mobil 1 though cause it's cheaper (Costco) and can be found anywhere.
