Im sure this has been covered before, but I was wondering if a good synthetic 0w-20w or 0w-30w was a good idea for the cold winter months. I started my car the other day and it knocked a little until it warmed up. Kinda freeked me out. The engine has been rebuilt, and has about 1000 miles on it, using conventional 5w-30w, and the temprature was around 20 degrees farenhiet. I know it will reach -30 before winter is over and thought a lower viscosity oil would be better suited. Just wanted to run it by others who see the same type of tempratures as I do here in Idaho. |

Wow, that's some cold temperatures. Synthetic oils are generally less affected by temperature extremes. I would think a synthetic 5w-30 should be fine. I'm sure others will chime in on this relentless pursuit of petro perfection... |

If you can get the 0W30 that might be even better for a below 0F start up and a coolant or block heater would be a great idea IMHO.

0W-30 is a great idea for winter. If there had been such a thing when our cars were made I'm sure they would have recommended it. I personally think that a synthetic 0W-20 would work, but this is definitely outside recommendations, you're on your own if something blows. |

No kidding, your driving a car well outside of warranty, buy a second crappier version of your model and experiment to your hearts content

5w-20 synthetic blend is the best value for the money. It is made out of great base oil stock and has an excellent shear rate. All the benefits of a free flowing synthetic, but at half (or less) of the cost. |

I have been running Mobil 0w-20 for awhile now. No explosions yet. |

I guess a good test is after 60K or more pop the engine open and check the wear patterns on oiled surfaces

In that situation I would prefer to test by turning the key and driving off,.

Thanks for all the posts I tried mobile 1 0w-30w and the noise on cold starts below 20 deg has stopped, The lifters seem to have stopped clattering also "bonus". So far I'm impressed. Seems the extra cost of a fully synthetic oil may pay off in thel ong run. |
