truth about synthetic oil
I was thinking of changing my oil from mobil 1 0w-40 to 5w-40 as i dont drive in the winter, and as i was doing some research on various brands , i came across this. Below is the excerpt from different forums , what do you guys think. i think i am going to go with motul 8100 5w-40?
" motul x-cess 8100 5w40, its a true synthetic oil with ester based group V basestocks. castrol german 0w30 is a real synthetic, group IV PAO stocks most "synthetics" arent synthetic at all. research what you use and you'll find out that 99% of synthetic oil really isnt synthetic, just processed group III oils like mobil 1 synthetic and castro syntec " and they are allowed to call them synthetic as they are highly refined by the court" |
Ultimately it may not make a lot of difference, but I personally will only use what Porsche has recommended.
Having said that I have used Mobil 1 for all my vehicles (Mercedes - recommended and Nissan's - not preferred) for about 15 yrs. |
so what is true synthetic? is it something that is chemically produced?
i predict the next trend in oil is ORGANIC... :D |
I agree with ruf_turbo. What makes you think that Mobil 1 0W-40 is not 100% PAO stock? Just because you don't drive during the winter doesn't mean you don't get the protection of 0W-40 or that it is less protective than 5W-40. The lighter viscosity means that it is more readily distributed upon cold start-up, regardless of temperature. There also may be a concern mixing PAO stock with ester stock but that is debatable.

my advice is stick to the doctor's description ;)
TTDude u disagree i totally agree ;) |
I think that at some point we have to stop second guessing Porsche. :)
Believe it or not, they do spend time researching stuff like what oil is best suited for their engines. ;) |
When I first sent in an oil sample to Blackstone Labs for testing I talked to one of their chemists. He told me they don't see much if any difference between any of the various type oils. When I asked him what he used in his car he told me the cheapest stuff he could find.

Are you following that chemist's advice yourself? |

As I posted in other threads about oils, changing the oil more frequently is the key to keeping these cars running STRONG. I drive 2000 miles a year and change the oil twice. When I drain the oil it looks worn, not like 1000 miles of driving a Toyota or Honda.
I use Mobil 1 - 0W40, 5W30, 5W40, or 10W40. Makes no difference because I live in So Cal (close to the beach) where the temps range from 50 to 75 -90% of the time. |
