Check below for the correct fluid specs for various models of Toyota 7 and 8 series trucks. But first, here’s a short explanation of some abbreviations that you might come across.
• API = American Petroleum Institute classification. The API classifies lubricants based on performance level and series. Read more about what those classifications mean here.
• SAE = Society of Automotive Engineers classification. This is a classification based on the viscosity of the lubricant.
• ISO VG = International Standardization Organization viscosity grade. This is another measure of the viscosity of the lubricant.
