Hello, I have lurked occasionally into these forums , but now I need some advice or opinions on the move from dino oil to synthetic.
1. I have a 1998 olds intrigue with 32000 miles. The car had 10,000 miles on it until I purchased it last April and is in great condition. I normally drive about 50 miles per day on my commute so I average about 17k per year. Until now I used dino 10w30 in summer and 5w30 in winter with a 4k oci. Looking to reduce my time under the cars for oil changes so I would like to switch to mobil1 full synthetic. I have bought 15 quarts of 5w30 Ep with the ep mobil1 filters and was thinking of running this year round trying for a 8.5 to 10k oci. Does anyone see a problem running 5w30 in the summer in Wisconsin the engine is a 3800 series 2? I thought 5w30 would be better due to the short summers and longer periods of colder weather.
2. My wife has a brand new 2009 Pontiac vibe with the 2.4l Camry engine. She drives about 90 miles a day. With 28k yearly average. THe first change will be dino oil from the dealer for free and they want us to do that at 2.5k ( they say to remove the break-in oil, i thought that was a thing of the past), so i will be taking over with the oil changes at about 7.5k Was also looking to spend less time under the hood by going full synthetic as well. Does anyone reccomend going longer with dino oil to break in such as waiting a few more changes? The car now says 5w20, but I know that is for CAFÉ standards and that the Pontiac dealers all use 5w30. Do you think it would be good to use mobil1 EP 5w30 in this car as well; it sure would make things easy. Also weather I use 5w20 or 5w30 on this car do you think I can do 7.5k oci or more gm book says 5k, but that is only around 2 months for her and at that point I might as well use dino oil. If I go for a longer oci do you think the mobil1 filters are best, or would a pure one, wix, or Toyota OEM be just as good?
Sorry if this is a lot of questions but I have been saving them up for a while
Thanks,
jpamp
