OK so I tried searching the forum for a topic discussion on engine oils but unfortunately topics are restricted to certain car brand within car subforum
Would like to gather all car enthusiast opinion here.
From my understanding
There's mineral, semi and full.
Since this is best of the best topic we will just talk about full.
Full synthetic is group 3, group 4 and group 5. 3 being refined from crude oil
4 is PAO and 5 is ester based.
So many advertisement and testimony with pictures of cars clocking 200k km above using chemlube ester based oil open up gasket not a single deposit of carbon found.
So my ques:
I have a 10yr old nissan Latio sedan 1.6
Nv really bother much on its performance last time (point A to point B workhorse car). Used semi synthetic for 8 years and now total quartz 9000 10w40 full synthetic 2 years.
If I use ester based oil would it slowly clean up the deposits on my car?
Plan to foam clean the valves and throttles and engine flush first next change
Another ques is for newer cars.
If say I have new nissan x trail 2018 and still under warranty would using other oil void the warranty?
And do cars like myvi icon 1.5 worth putting ester based oils if I go long distance and 60 highway 40 city
Is the price diff worth it?
Brands wise?
Torco Millers CFS NT
Chemlube

For me my personal favorite would be Royal Purple's HPS for FS oil. One of the smoothest oils i've ever used and pretty good FC + anti wear & detergent additives inside.
Amsoil also has pretty good oil, but somehow it doesn't get as good FC results as RP. The entry level ones also cant hold oil pressure + shed heat fast so I didn't like that . Their manual transmission oil is crap also, but ATF & Powerfoam pretty good. Been using it for a few years now.
But for a
cheap daily FS I normally go to Bardahl + 1 can of B1 because of price.
Just a little extra for cleaning high-mileage/old neglected engines: I'm biased to Bardahl's engine flush because I managed to get a bit better ring seal from a friend's 1JZ when I serviced it awhile ago. Plus you can drive with it (not hard of course) in the engine oil.
Marvel Mystery Oil is good stuff too, but that story is for another time...
