Soon LSPI will be a Well Known Acronym

AMSOIL once again leads the way into a ever changing industry

As the majority of engines add the latest fuel and mechanical technology to increase power and fuel economy, the majority of motor oils are not anywhere close to dealing with it.

I recently returned form the AMSOIL U Live update training they have at the headquarters in Duluth/Superior, WI. We got to see the commitment to lead the market once again with upgraded oils which can do what they’ve never seen an oil accomplish before. These new upgraded versions of the OE, XL and Signature Series will undoubtedly lock AMSOIL and their dealers into solving this LSPI issue head on.   We will be preventing the costly damage customers of other brands will have to endure.


Yes – these modern engines will not make it through the intersection using conventional or so called “Fully Synthetics” so the old adage of “As long as you just change your oil at 3000 miles you’ll be alright.” will no longer apply.  Even if you changed your oil at 50 mile intervals, if it’s a conventional or run of the mill synthetic motor oil with any of the common volatility ratings, the high temperature GDI compression stroke will not do well for them..

Our competitors will improve too but at best they will only be as good as we were before these upgrades!!

What is LSPI?

Perfect Score
LSPI is a hot topic in the lubricant industry. Auto manufacturers need to extract every bit of fuel economy from the vehicles they produce in order to meet increasingly stringent government regulations. Manufacturers can make fuel-economy gains in today’s vehicles by adjusting vehicles’ programming, but those changes would also almost guarantee LSPI would occur. LSPI’s often disastrous effects (see image) are one of the driving forces in the scramble to create the new motor oil specifications, API SP/ILSAC GF-6 and GM dexos1 Gen 2. To gain about 10 percent more fuel economy, auto manufacturers will eventually reprogram their vehicles to maximize mpg, inviting LSPI and relying on motor oil to prevent catastrophic results.

LSPI Piston Damage. Low Speed PreIgnition

While we expect this switch will be a couple of years out yet, we have dedicated considerable resources to confront the problem. The testing has concluded and the results are in: all AMSOIL synthetic motor oils provided 100 percent protection against LSPI in the engine test required for the GM dexos1 Gen 2 specification.

This specific test records an oil’s ability to prevent LSPI. Five LSPI events can occur before the motor oil fails. Signature Series, XL and OE Synthetic Motor Oil all passed with zero pre-ignition events, proving they provide outstanding protection for turbocharged direct-injected engines.
