Cold climate
Built for the morning the truck has been sitting at twenty below.
907 Synthetics exists because the oil that works in Phoenix does not work in Wasilla. Fredric Riech is an Independent AMSOIL Dealer in Wasilla. The job is to put the right 0W grade in the crankcase before the starter has to fight a pan of gel.
Signature Series gasoline oils and Max-Duty 0W-40 diesel are the two bottles we recommend most. Confirm the spec on the lookup, then buy through our store so wholesale pricing follows the account.
01
Wax is the enemy
Conventional oil is refined from crude. Wax is inherent. When the temperature drops, those crystals stack and the oil stops pumping long before the bottle’s 5W grade implies. Synthetics are built without that wax.
02
Wear is a cold-start story
A huge share of engine wear happens in the seconds before oil pressure comes up. In the Mat-Su that window is longer, more often, and at a lower temperature than almost any lower-48 duty cycle.
03
0W-40 is a year-round oil
The number before the W is winter. The number after is hot viscosity. A 0W-40 diesel oil cranks at −40 and still protects a loaded truck on the Parks Highway in July. You do not need a seasonal swap.
04
Anchorage ships it
AMSOIL runs a distribution center in Anchorage. Alaska orders often leave from there instead of the Lower 48. Preferred Customer and Dealer pricing still apply.

Watch: AMSOIL vs. conventional oil at −40°
A conventional 5W-30 and AMSOIL Signature Series synthetic, both chilled to −40° in the lab, then tipped at the same moment. That pour is what your oil pump sees on a January morning in the Mat-Su.
Cold-start gauge
Drag the temperature. This is an educational model of pour point and cold cranking — not a substitute for the OEM spec on your dipstick. AMSOIL pour points come from AMSOIL data bulletins; the conventional-oil values are illustrative.
-20°F
- Sluggish — wear window
Conventional 5W-30 (illustrative)
Illustrative values only. AMSOIL does not publish a conventional-oil figure; conventional oils contain waxes that thicken in the cold.
Illustrative pour point −22°F (not an AMSOIL figure)
- Pumps and protects
AMSOIL Signature Series 0W-20
No wax. Built to pump on a −40° morning and still hold a 25,000-mile drain.
Pour point −65°F (AMSOIL data bulletin G2880)
- Pumps and protects
AMSOIL Max-Duty 0W-40 Diesel
4X better cold-temperature performance than SAE 15W-40 oil in the ASTM D5293 Cold Cranking Viscosity test. The diesel grade for the Interior.
Pour point −54°F (AMSOIL data bulletin G3467)
