... thanks for that. I have an update that happened just a few seconds ago. My mechanic located a dealer here in Dubai that has Redline 5W40. So that is good news.
The main plan right now is to find a good budget solution using stuff that is easy to obtain locally. There is a dealer for HPL here in the United Arab Emirates, that is why I brought it up. It would be easy to get if Redline is not available.
In my mind right now is to try the advice in the link I posted - about using the Seafoam And then change the oil after about 20 miles of driving. I was thinking of using Castrol Magnatec 10W40.
I was a bit of reading and it seems that one reason the tick appears, is on vehicles that do a lot of short 15 or 20 minute trips in traffic; where there is quite a bit of idling. That pretty much describes quite a lot of my daily driving and usage.
Reading online, it seems that Castrol Magnatec was developed for that usage case and so that is why I'm thinking of giving that a shot over Castrol EDGE. If that doesn't work, I will change it and put in Redline 5W40.
If this plan works, and the Castrol Magnatec 10W40 does assist in eliminating the tick, I continue using Castrol Magnatec and but slowly go down to a 5W40 and then to a 5W30 - adding seafoam before every alternate change.
But that is a big IF. I'm willing to be a guinea pig in this test.
