Royal purple! Best detergents in the market! Highly recommended since your OCI is so short. A little overkill if you ask me though (the 5k OCI with fully syns).
And BMW liners are the best there is for that sorta money. Any more than that and it's overkill.
Why are you guys so obsessed with the 0 weight or 5 weight? It doesn't bloody matter in Malaysian weather, but the only real difference is engine startup on cold. 0, 5 or 10 would definitely do better than 20 or single weight oils.
I dunno. I've only tried two oil changes with Royal Purple but the UOA was better with German Castrol! This was on the SAAB.
It does make a different with what weigth of oil you are running for performance & logevity of engine.
Thinner oil does gain a little of performance. Thicker oil will get a little more wear protection. Just like anything else, there are limitations. Too thin or too thick are not good. Imagine swimming in a pool of mud vs water. Many race motor uses thinner oil to gain performance but the engine will be rebuild after every race. As for most of us, we choose longevity.
The one thing is that thicker oil also increases drag and engine wear sometimes particularly on a city car used over short distances where the oil doesnt get up to temperature... I'm a fan of using the thinnest oil possible which doesn't wear the engine (seen through UOA) and doesn't drop off oil pressure as it gets hot.

So where were we... Ah yes, the paint job!
After what was really months of sanding, primering, sanding, filling, primering, sanding, filling (you get the idea) we finally sprayed some colour on it!
At this stage I was over the moon! Considering it was off the gun and unpolished it was both pretty flat and shiny. Truth be told, I needed the encouragement as after 3 months month of seeing your car in a million pieces, you start to wonder if it will ever go back together again properly, and wonder if you have the persistence to pull through with the project.
While I was clear in my mind that I wanted the car in Estoril Blue as it came off the factory, one of those things we don't get the luxury of here in Malaysia is the same paint brand that the car was sprayed with. For this car I specified
HBBody high solid clear for the bulk of the car, and the famed
Glasurit 447 for the front bonnet, quarters and front and rear bumpers.
I have been using Glasurit products for a long time, but honestly the 447 while having good durability against stone chips etc doesn't shine as well as a good clear, so I wanted the sides of the car to show off all the prep work which went into it...
So then after the base colour and clearcoat had hardened for 8 hours we hit it with sandpaper again!
This is done so that the paint is absolutely flat before the final coat of clearcoat went on...
Its pretty depressing seeing the car go from red to primer to colour to shiny and then to matt all over again.... but you gotta do what you gotta do to get the result you want...
Thanks for reading! Keep the feedback coming.
