Owner reviews for engine oil

I recently switched from Liqui Moly to Amsoil recently, my wife's Tiguan seems to run a little smoother and is noticeably quieter at idle with the 5-40 European car formula.

Its not uncommon for a new Tiguan to use oil. The new oil is really thin. It is VW special,you might as well go to the dealer and purchase a quart.

I'm at 80,300 miles, original owner and I just changed the oil, first time I tried Mobil 1 ESP 5w-30 502.00 504.00 507.00 and the old R is idling quieter than ever, previously I was getting some slight timing chain noise but now its gone.

My 93 loved and my 94 loves Rotella T6 5w40????????

Amsoil is just an above average full synthetic oil. It's nothing magical. It has a higher than normal "Total Base Number", which is what allows it to go longer between changes without going acidic.

I'm running 5qt 5W40 full synthetic oil (Castrol Edge, to be specific). The oil is changed yearly cause I never get close to the 10k miles suggested by VW for an oil interval.

I might try comma motorsport 5w50 when the summer comes though.

Used mobil-1 on my 2015 corolla for 156k miles zero issues. Have used Mobil-1 0w-20 on my 2018 Camry for 65k miles and this point I have had no metal deposits for the whole duration.

For the FA20, I like Rotella T6 Multi Vehicle 5w-30.

Engine runs super smooth with that oil.

Used to use Motul, now switched to Red Line for the higher zinc content and high heat stability. I rallycross my daily so high RPM and high heat.
