Using fully syn oil will be protection for engine in long run.
You have to understand the real main benefits of fully synthetic oil before making statements saying it will be protecting the engine in the longer run. If you understand the application, you know where to save money without the detriment of the car.
Why i don't choose fully synthetic and just go for the free semi synthetic oil :
1) oil change interval is 6 months or 10,000km
- Any properly formulated semi synthetic oil can more than last this schedule under normal driving
- Any oxidative stress that may occur is (in my opinion) not off the charts as confirm change within 6 months (not a year)
- The TBN of the semi synthetic oil is actually quite high as it meets ACEA A3/B4 standards (which is minimum 10). Very unlikely to deplete the TBN at that interval unless the petrol is very very bad quality.
2) this is an NA engine, not turbocharged
- temperature stress on the engine oil is not that high
- stresses on components also lesser as less power is produced, means less shearing
3) the SC price is a ridiculous. It is not a top up price, it is like you buy a fully synthetic jug and MSRP and they get to keep the free oil, instead of rightfully discounting the cost of the semi synthetic oil when you opt for fully synthetic during oil change. In short, earning both ways.
4) most SC stock 5w40 for fully synthetic while semi is 5w30. 5w30 is lighter viscosity oil and it means some marginal fuel consumption benefits compared to the fully synthetic version. Also, lighter oil means faster circulation, also means the engine can run a little cooler, which i think is better under our hotter climate.
5) last but not least, semi synthetic package is free, just go in empty hand.
Anyway, your car, your call
