I keep on hearing that synthetics "last longer", but I don't believe that's necessarily true. Probably the most important thing for "extended-drain" is the additive package. |

Again, the ACEA A3 (extended drain) is met only by Mobil1 0w-40 and 15w-50 weight oils in America. There was someone on an NG who produced a list of the Mercedes- Benz recommended oils for their regular and extended-life service. |

Synthetics generally 'burn off' some of their qualities slower than their mineral counterparts.

cleaner than conventional oils, which tend to leave deposits as
they burn off. OTOH - more "conventional" oils now use Type II/
III base oils which are supposedly improved in this regard. A
good synthetic should also be less volatile than a similar
conventional oil.

Any benefits to getting my oil changed with synthetic oil? I called the Toyota dealer and they said it is better. |
Purolator, Delco, Mobil-1... stay away from Fram), you can extend your
change intervals to the max allowed by your warranty.
After you are out of warranty, you can extend your intervals to the
max allowed by oil analysis, but honestly, it would be cheaper to
continue changing at 7500 than pay for analysis every 3000 until you
need to change at 15k.
Go with a REAL synth... Mobil-1 or Amsoil. The cheaper synths like
Mobil-1's blend and Castrol are blends and not pure synthetic.
If you're the kind of person who keeps a car for three years and
trades it in before it's got 100k on it, you will not see any benefit
from synthetic.
If you are like me and drive them to the junk yard, you'll see a big
difference.

Probably the most important thing for "extended-drain" is the additive package. Most heavy duty trucks run on conventional extended-drain oils for diesels like Shell Rotella T or Mobil Delvac 1300. The additive package is likely to be depleted before the base oil "wears out". Those are excellent and exceptional oils for the intended use. I wouldn't use them as the benchmark 'average' for most petrolium oils as they are far above that. However - the typically available 15W-40 isn't close to a recommended weight for most passenger cars. I could imagine it might be suitable in cars/light-trucks used for towing. |
cars. I am using it in my '93 Dodge Caravan 2.5L which leaks oil at the
valve seals to minimize oil loss [I do use a thinner weight in winter].
BTW, Shell also has a Synthetic version of Rotella T at 5W40 which is in
line for use with most Toyotas. It is a little cheaper than Mobil-1 at
Walmart in gallon jugs.
