You can't tell me they put 5000 miles on these engines during testing, drain the dino out of them, fill them with synthetic and then install them into new cars. I switched my Subaru to synthetic at about 1500 miles and my wifes Jeep Cherokee to synthetic at less than 1000 miles. The Jeep has over 160 on it and uses no visible oil in 6-10K OCI's. The Subaru now has 20K on it and uses no visible oil-the OCI's have been less than 6K to stay within warranty requirements. 06Ranger, give it some time. You could simply have additional oil up in the engine that didn't all drain down into the pan. 1/8" less on the dipstick is nothing to worry about.

quote:How soon after the oil change di you check it .... minutes.... hours... days? Was the vehicle on a flat surface.... sloped? Did you use the exact same oil filter as OEM? If the vehicle was not moved when you first checked it to see that it was full, then it's possible that the oil filter was not completely full at first. With new vehicles, you need to drive the vehicle after an oil change for a couple of miles -- park it on a level surface -- let it sit overnite -- then check it for a true reading the next day. That's how you arrive at a more precise reading on the dipstick.
I changed to Syntec at 1k miles it's not factory fill and I checked it after the change and it was on the full mark. Today it was probably 1/8" down from the full mark ... stil more than 3/4 full though.
