So, using Full-SAPS and more frequent OC seems a happy medium?
Yeah, load will help. If you run your car 80mph in 4th gear, it will not help. Pushing car hard for extended period of time (1-2 hrs) will help. Accelerations etc. If you have some back road where it is safe, I would use it to push car.
Also, if you think you cannot do that that often, start using immediately these two oils to address that issue, and change it every 5K
1. Motul X-Clean 5W40
2. Pentosin 5W40.
Both are Mid-SAPS.
Thanks!
So, IF one can load the engine, using Full-SAPS works okay? Or are you saying Mid-SAPS regardless?
Where do you buy your ^suggested oils?
I always used Full-SAPS. I experimented with M1 5W30 ESP low-SAPS. it is great oil, but low TBN which is a problem in combination with the U.S. gas. Due to the emission regulations, market price of VW in the U.S. third gen of those engines are not coming to the U.S> with port injection like in EU, so eventually some carbon will show up on your valves. How bad? Do not know, I do not have any problems on my CC with 88K.
Where do you live? Are you in California? If you are in CA then you can try Low-SAPS oils and then send it for UOA to Blackstone to check TBN.
This is first time I am using Pentosin 5W40. Local small shop carries it here. It is $44 for 5ltr, compare to $27 for Castrol or M1 0W40 in WM, so it is more expensive.
If you do not have locally, you can order online on: FCP Euro, ECS Tuning, etc etc, just type in that oil in google, and bunch of web site will pop out that carry those oils. If you live in hot area with mild winters, go with Motul X-Clean. It is Full Synthetic PAO oil. If you live in norther states, Pentosin will be better since it has better pour point.
Whatever you choose, Pentosin, Motul, Castrol or M1 0W40, you will do much better then what dealership puts in. Then just find local road, and push that car hard, or track. BUT if you do track, be careful when it comes tp tires, brakes and brake fluid.
