1992 Saturn SL

Reader Question: Hi Austin,

I drive a 1992 Saturn SL (196,000 km) that is still in very good condition. I am thinking about switching to pure synthetic oil at my next oil change.

From what I have read, it seems synthetic oil is superior to petroleum-based oil, especially in terms of low and high temperature viscosity performance.

My questions are these:

1. Do you think making the switch to synthetic is wise? (Is it better for my engine in the end?)

2. Should I get my engine flushed at the time of the switch?

3. Which brand of pure synthetic do you think is best?

Thanks very much for your time.


Hi there Leelan,

To be honest I think with that mileage you already have on the engine. I would continue to do what you have been doing and not switch at this late in the ball game.

Of course, many people swear by synthetics and would recommend you start using it like 4,000 Km ago…hahah!

Have you read the eBook The Motor Oil Bible? I give it away from here if you have not read it yet. It will tell you everything I mean everything you want to know about oil.
