Hey everyone at 100,000 I switched to 10-30 Mobil 1 synteic everything is fine, even drove to Florida to NYc 2 times.
I am currenly using 4 quarts of Mobil 1 10-30 and 1 Quart of Lucas Synetic Stablizer. People tell me this is a waist but it helps me sleep. First of all is this combo any good and how often should i change the oil with the type of combination, bare in mind my car does have 138,000, but runs GREAT. any advice is welcomed, thakns alot iam currently changing every 5,000
