This is my first oil analysis. Analysis was done by Ramatek in Calgary.
Oil and air filters are Toyota. Oil has been Toyota 0w-20 for the past 4 OCIs. Last oil change was 2011-09-02. Oil sampled 2011-12-15 at 61,020 km. No top-up oil and no apparent oil consumption. 90% highway, 10% city. The car is not used for commuting as I ride a bike year-round (it is usually faster and I get 40 minutes of exercise per day as a bonus). I drive gently for the most part, and never flog the engine until it has warmed up.
A bit of history: The dipstick has had a gasoline odour since the car was new - not raw gasoline, but a gasoline odour. I was concerned about fuel dilution. Someone I work with has the same car/engine and his dipstick also has a gasoline odour. I went to Ramatek to get a sample bottle and David, the owner, offered to draw a sample on the spot so I took him up on the offer. I was going to change the oil in a few weeks when the OCI reached 8,000 km and take a sample at that time. David's way was easier.
Toyota recommends 8,000 km OCI regardless whether the service is considered severe or normal. I've been using Toyota's recommended OCI.
I was surprised by the results. I obviously have an air intake leak problem. When I changed the air filter at about 44,000 km the parts counter guy said there were 2 air filters for the 4-cyl model and my VIN wasn't enough to establish which filter was correct. He looked at my filter then provided what I thought was the correct filter. I'll be getting a new air filter (probably both types) tomorrow and get the filter issue sorted out then change the oil. I'll do a thorough inspection of the air intake system to see if I can spot any potential leak spots.
