AMSOIL Product Cold Temperature Storage Recommendations

As extreme cold temperatures can have a detrimental effect on the performance of some AMSOIL products, they have offered some winter storage recommendations for each product category.

You may look at these recommendations and wonder what will happen to these lubricants if they freeze below the listed thresholds once installed in a vehicle. Apparently temporary freezing is fine as the vehicle will be brought into service and warm up the lubricant. We are told that if a product is stored below the listed temps for weeks on end, that it can have a negative effect on the additive package of the product. Temporary freezing will not be an issue and of course there are no better products for your vehicle in frigid conditions.

On a related note, the shelf life of the AMSOIL synthetic lubricants is 5 years, across the board.
