I've decided to go with the Penrite HPR5. I've chosen Penrite based on the recommendations of the members here. I think that HPR10 would be great as well, but Penrite specifically recommend HPR5 for this car and that's based on the expected temps we have here and the SAE rating being more relevant, but it's not a super critical difference. Recently we've had some very low temps here so the HPR5 product does make sense.
I won't use the Magnatec anymore based on the recommendations here, just to be safe.
Synthetic is definitely the way to go as the technical benefits are clear; primarily more reliable temperature control and far less impurities.
On the question of the flush, there doesn't seem to be any real risks in using it, the overwhelming information on the web is that it's a plus and we have our own Madmagna's expert recommendation as well. I feel it will help to remove some of the built up deposits more efficiently than simply doing more frequent oil changes would. Certainly I have not seen any recurring problems mentioned about engine flushes and the people I spoke to could not identify any problems either.
I will do the flush, drain/fill and drain/fill (so double drain and fill) as that reduces the risk of old additives/oil/detergent left behind after the flush. Overkill? Maybe, but small price to pay to mitigate the risks.
Only problem is availability of getting this done as everyone is booked up for some reason and I want this done ASAP. I did find someone who can do the flush for me tomorrow and I've got the second drain/fill booked for Saturday.
I'll then do the next couple of services at 5K intervals and by then I expect the crankcase should be nice and clear and this issue resolved.
After that I'm going to do the servicing every 7Ks which should ensure longevity of the engine components over time. I think the recommended intervals of 10Ks is just too long, based on my reading of all the pros and cons.
I read your concern regarding the flushing of your engine and I would like you to go to this site www.auto-rx.com and read about what I consider is the correct way to flush an engine.
I did put into consideration what they claim that the product can do and I decided to give it a go BY ORDERING 4 BOTTLES US$ 93.08 + P&H US$ 43.65 = US$ 136.73 (US$ 34.18 each).
I own a Verada KW GTVI AWD II 58800 km and after having read all the problems that go around with the wave spring in the AUTO/TRANS I believe that I can use this product in my AUTO/TRANS and after that a simply oil change will do the job. The good thing is that there will be some remnant of the product that will stay in the box working in there forever. The company clearly states that if I want to do a flushing, I have to do it before applying the product and after that to follow the procedure before mentioned.
I hope that these humble lines might be able to give another insight in what you, I and perhaps some other Magna/Verada owner/s might consider to be a very important issue regarding the care of our ENGINES AND AUTO/TRANS.
