FIrst of all is the car designed to run on synthetic oil only? (what kind of car is it?)
Second of all, - I wouldn't go back to conventional oil as you might notice different engine performance...kinda like going back from Menzerna polishes to turtle wax...

I find nothing wrong with dino oil. Synthetic may give you those extra few ponies, but it does so by being a very light oil, and tries to make up for that protection loss of being light in with other methods. This simply means that while the oil itself will not break down as fast, these additives will still break down, leaving you with a relatively light oil in your car.

I see it this way: No matter what, you will get engine deposites in your oil; that is just normal wear and tear. As long as the oil doesn't break down, both synthetic and dino will infact offer the same amount of protection so long as you use a quality oil. The real-life difference is going to be that you are going to change the dino oil more often, which can be seen as a good thing as you will flush out all those deposites more often. Provided you know when your oil needs to be changed with a UOA, an engine that runs on Dino can run just as long as a synthetic oil engine. Now with synthetic oil, you can extend those periods of oil change, and provided the additives keep up in the oil, it 'can' save you some money. Remember though, as the additives wear down, the amount of deposites that get in the oil increase. The key here is to get a UOA on both to find out how often you need to change your oil with both, and then judge by how much it costs to how long they lasted.

As for performance, I highly doubt you will notice a difference. In real life terms, we are talking about 10hp on a high performance engine, and even less on anything less. For me, I will stick to Castrol dino oil and change it often because even though the synthetic oil may last longer, you still have the oil filter which gets clogged and should be changed every 3000 miles anyways. For as cheap as dino oil is, I just do both at the same time, and rest easy in the knowledge that my engine is VERY well maintained.

Now I know it may seem like I hate synthetics, but that just isn't the case. For my situation, I find dino to be the better choice, however your situation may differ. I can not stress the importance of trying different oils and getting UOA at different intervals to find out which is better suited for your driving habbit/car/environment.

Thanks a lot for the info!

This is a myth. I highly suggest you browse the BITOG forums: Bob Is The Oil Guy - Powered by UBB.threads™

It will answer any questions that you might have about oil. Synthetic is good if you want to run extended oil change intervals, you race your car, etc. However, if you want to sleep easy at night by sticking to the recommended OCI and not spending more than you have to on oil, dino works great.

I use synthetic because I run extended OCI's.
