Posted the second UOA for my wife’s 2006 Pontiac Vibe on bobistheoilguy.com for review.
Everything remained fairly constant between the two samples. The AMSOIL XL line of oils is a pretty stout product. We ended up pushing it out to 14,000-km/7-months which is a month overdue on time and 2,000-km under in mileage for the product service life.
I received the used oil analysis report from the Oil Analyzers lab in Edmonton and posted my results on BITOG to get some feedback.
I’m not happy with the fuel dilution in the report but the lab technician seems to think the oil is fit for use for another 5,000-km. I’m interested to see how the fuel dilution number changes as the oil approaches its end of life.
Other than that everything looks good to go for 15,000-km/6-month OCI’s in Laurens Vibe.
Which AMSOIL tier is best for my vehicle?
This can be a tricky question that can depend on quite a few variables including: cost, value, oil quality and extended drain interval expectations. The best way to start the discussion is to introduce the 3 tiers of AMSOIL synthetic oils available:
- Signature Series = The top tier product that has a drain interval of up to 24,000-km/1 year
- Extended Life (XL) Series = API certified middle tier product for those that prefer to change their oil twice a year with a drain interval of 16,000-km/6-months
- Original Equipment (OE) Series = API certified introductory tier with the lowest cost synthetic in the AMSOIL line for those interested in trying AMSOIL products and maintaining manufacturer warranties by using the drain interval specified by the equipment manufacturer

AMSOIL’s Signature Series line of products has a service life of:
Normal Service – Up to 40,000 kilometres or one year, whichever comes first.
- Severe Service – Up to 24,000 kilometres or one year, whichever comes first.
Here in Canada everyone is limited to the Severe Service schedule so that simplifies things even more. But knowing the service life of the product doesn’t mean you can simply forget about your oil or your vehicle until the mileage or the time expires. That is the same service interval as 4 “normal” oil changes!
Below are some situations when you should check your oil level:
