I'm cheap now. I buy Shell Helix Ultra for RM99
The boat is seldom driven, so I change every year instead of following OCI.
Any perceived difference when u drove with shell vs amsoil? I also store shell in my storeroom for my less driven cars. Hence I can't make the difference. Those cars nv go to highway. Only around penang Island

1 year is ok, heck even myself on shell helix ultra 1 year oci. Less than 10k km.
As you know my VR running Pennzoil HDEO 15w-40. Suppose to change every 6 months since very low mileage, Recently was busy so push to 8 months since mileage only 1k plus km, but after change can feel the smoothness of the engine......lol

Difficult to say since you aren't comparing apples to apples (15W40 isnt synthetic)

When I first use FS, I did keep OCI at 10k km, but my engine seems very dirty (meaning oil quite dark), thereafter I change them earlier also.
Was suppose to use this HDEO to flush the engine, but my engine ran quieter, that is why I start using this oil instead.....lol

My ass can't tell any difference. But I can tell you running 3 years with a mix of Amsoil SSO and German Castrol, my turbo was pristine condition. Cause took it out to fix a leak on the hoses, so checked the turbo again.

penzoil longlife Gold? 15w40 mine also switched on this oil for recent work on the engine...

seems like working exactly the same as my previous 20w50 of castrol CRB multi.... :biggrin:


if my engine totally no leaks afterwards will opted for penrite HPR racing oil later....with no leaks...definately would waste a good oil.. :driver:

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. :laugh:

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. :biggrin: Marvel Mystery Oil is good stuff too, but that story is for another time...
