Hello, this is my 1st post on here. Have visited site for about a year but haven't really had questions or advice (lack of Knowledge) to give. Thats just a couple of excuses to why I haven't posted until now. My question is, my girlfriend purchased a Vue a while ago. When I were to change her SUV's oil the cost to get the filter was outrageous. 9$ for a regular filter. I could understand buying mobil 1 or redline, or even K&N, and pay that much but wow. So I decided to change the Vue from Valvoline 5W-30 All Climate to Mobile 1 Super Syn. 5W-30 and do 9,000 mile changes. She has run about 6,000 already and the Vue hasn't used a drop of oil yet. I decided to look down into the oil spout in the valve cover and when I removed the cap I saw some white greasy looking substance around the cap and threads of the spout. The exhaust cam looked really clean with no problems. The oil smells great, no gas dilution detected by the smeller. Curious to know what that might have been. I plan on doing an analysis at 9,000 to see how the oil performed. Would like to switch her over to GC but not sure if it can go 9,000 or not. I haven't seen to many posts showing 9,000 mile + intervals using this oil. If you can show me otherwise, I will switch it over. Local autoparts always has about 12+ quarts of GC. Thanks for any help.
