Zic's synthetic oils

[osiraj]

Oil Grade (API Classification) especially WEIGHT of Motor Oil and i stress again WEIGHT should be according to manufacturer specs. Please understand it depends on bearing tolerances in the engine where Oil needs to form a layer to avoid excessive wear.

So a motor oil 10W 40 maybe good for Suzuki or Toyota but may not perform good enough in a Honda engine with tighter tolerance levels. Though many ppl endorse Zic motor oil but I have used Total 9000 Future 5W30 for years in all Hondas with great results in terms of fuel economy, power and engine longevity.

Multigrade oils use polymers that increase or decrease Viscosity of a motor oil according to engine temp. Cheaper oils run out faster need to be replaced more quickly than Synthetics. Meaning oil additives and polymers are consumed faster. With time these oils will not form protective layer good enough to avoid engine wear. Having said this although Synthetics are better but change interval is not as long as abroad. In Pakistan engines are subjected to poor Fuel Quality and Dusty Environment which drastically reduces oil change intervals.

Therefore for Stock engines please refer to your owners manual and select an engine oil accordingly. I am more comfortable with Mobil, Total, Havoline than Zic Shell Fuchs Kixx or other Brands.

Our mentor zulfiqar disagrees that fuel quality affects the quality of the engine oil.
I've discussed it many people (including Mr. Steffen of Liqui Moly Germany) and all of them totally agree that Bad Fuel affects the Quality/Life of Engine Oil for sure.

From the above info it seems while Zic A+ and Zic 0W 30 may have similar base synthetic oil suitable for Gasoline Engines but XQ seems to be from a different Base Oil and possesses different additive formula. Also read MSDS for additional info on these ZIC oils. But then you will not get any info on the actual additives used in these Oils and their quality / quantity and concentration which differentiates their service levels and also price.

Our mentor zulfiqar disagrees that fuel quality affects the quality of the engine oil.
I've discussed it many people (including Mr. Steffen of Liqui Moly Germany) and all of them totally agree that Bad Fuel affects the Quality/Life of Engine Oil for sure.

Fuel affects the lubrication oil in different ways - e.g. as I said in DI engines, it sometimes can even destroy the oil in 100 kms. The new mazda DI engines even have higher than max reading on dipstick sometimes - because fuel is mixed in.

in regular IDI engines the PCV system's job is to keep the oil clean and healthy. Fuel is standardised around the world and engines are built for the specific requirements of such fuel. e.g. if the minimum requirements of fuel is 91RON in an engine and you are using 87RON - the engine will suffer as it will knock which causes other problems (low engine output).

That is not a fuel issue - its driver stupidity and no amount of "awesome oil" will change it.

I think in Pak. even Hi-Octane don’t have 91 RON. (smile)
As per defined standards, the RON has to be 91 for gasoline. But even very high quality fuel station (perhaps a few in whole Pak.) may have it.
Even more than 90% owners of the petrol pumps don’t know what is RON or about fuel properties, dyes (coloration), etc.
