Engine is the heart of the vehicle. I dont find any point compromising on the engine atleast. I feel better to cut a accessory or two from the list. The money that can be spent on adding accessory can also be spent on adding a better engine oil. And I dont think there is anything like synthetic oil is only for diesel engines.
The technical Advantages of synthetic motor oils include….
-Measurably better low and high temperature viscosity performance.
-Better chemical & shear stability.
-Decreased evaporative loss.
-Resistance to oxidation, thermal breakdown and oil sludge problems.
-Extended drain intervals with the environmental benefit of less wastes oil created.
The Disadvantages of synthetic motor oils include:
-Initial costs are usually three times greater than petroleum-based oils.
-The lower friction may make them unsuitable for break-in (i.e. the initial run-in period of the vehicle) where friction is desirable to cause wear. As many vehicles now use synthetic oils as factory fill, this is less of an issue than it once was.
-Potential on some older pushrod race engines with roller lifters for the roller itself not to spin with camshaft movement, but rather slide while the roller itself remains either stationary or at a lower circumferential speed than that of the camshaft lobe.
