Hi, recently bought an '04, and was wondering what type of oil you all use? Is synthetic better for our car?
Thanks |

| The normal stuff has been around for years and has proven itself worthy, a blend runs a lot smoother and withstand longer intervals, but for me, its been full synthetic all the way. Yeah, it a little more expensive, but IMAO I believe it performs the best. So, long answer short, it depends on your driving habits and environment. :29: |

Just use regular oil. You should be fine as long as you change the oil every 3k - 3 months whichever come first.
Check the manual. On 02 the manual says use 5w-20 but the cap say 5w-30. I use 5w-20 on winter and 5-w30 in summer. |

| 5w-20. I use regular engine oil. Synthetic definitely adds more protection for the money. |

Three months between oil changes is too soon unless you have fuel dilution problems. If you drive very low mileages, change it every six months if you do short trips and every year if you do infrequent but longer trips (> 20 miles).
If you do a 3k OCI, I would leave the oil filter in there for two changes. |

| I'm currently using Mobil1 synthetic 10w40 for high mileage cars on my 2001 X that has 117K miles. I don't know if it's going to make a difference down the road but we'll see... |

| Been using whatever the dealer puts in, which is Mobil non-synthetic every 4k-5k miles and no problems at 89k miles. Our Corvettes on the other hand get a strict diet of Mobil 1 5w-30 full synthetic not only because of their high performance engine characteristics but because the owner's manual calls for it. The owner's manual doesn't lie. :7: |

Did you say 10w40 ?? And you run that all year round ? Thats too thick for this motor! I am curious why would you do that ?
After experimenting a bit I have finally settled for a Synthetic 5w20.
Quite contrary to the popular belief, thick oil can sometimes hurt an engine instead of helping. If the oil is too thick to make its way between the piston rings and the cylinder walls, you will see excessive wear. It will actually wear out at a much higher rate than using a thinner oil.
On the same lines thinner oils, synthetics especially, manage to get theirselves into the smallest and narrowest passages of the engine so those areas get better lubrication than when using thicker oil. |

| I wonder why it's advertised for high mileage vehicles then? I was just experimenting at Walmart one day and saw this new Mobil1 variety. I used to put 5W30. |

Oil weight and the "high mileage" stuff are two different things.
There is a 5w30 "high mileage" from Mobil1 too. You should be using that, if at all you want to use high mileage.
I suggest you replace the oil as soon as you possibly can and replace it with a 5w30 or 5w20. |

In a word: marketing. |

High mileage equals worn parts.
Worn parts equals more space between bearing surfaces.
More space between surfaces likes thicker oil.
Thicker oil fills the gap better.
