## Description

Briggs & Stratton 100170 Vanguard 15W-50 Heavy Duty Synthetic Oil, 5 Quart

Review: Excellent Performance and Long-Lasting Protection! - I’ve been using the Briggs & Stratton 100170 Vanguard 15W-50 Heavy Duty Synthetic Oil in my equipment for a while now, and I am incredibly impressed! This oil provides outstanding engine protection, even under the toughest working conditions. I’ve noticed a significant improvement in engine performance—smoother starts, quieter operation, and overall better fuel efficiency. It’s specifically designed for heavy-duty use, and it really shows in how well it performs in my lawn mowers, generators, and other power equipment. The synthetic formula makes this oil incredibly durable, and I’ve experienced less wear and tear on my engines compared to regular oils. The 5-quart size is perfect for those larger engines, reducing the number of refills needed. This oil really helps extend the life of my machines, and I feel confident that I’m getting the best protection for my investment. If you’re looking for a high-quality, long-lasting oil for your heavy-duty equipment, I highly recommend the Briggs & Stratton Vanguard Synthetic Oil.
Review: It's made for it - Best price i could find for the 37hp big block on my mower. This is on the factory list for best lubrication in a large temperature range. It works and is high quality. I think I may go with a slightly thinner oil after the warranty is up. Should get better fuel efficiency out of 10w40. The engine should run plenty col with thinner as well.

## Questions & Answers

**Q: Can 15w50 vanguard synthetic oil be used on my Toro Recycler 22 inch mower ?**
A: I would not. I would stick to a good 30 weight or 10w-30. Splash type oiling systems are not good with thick oils.

**Q: I have an older vanguard and the book says sae 30 or 10w-30, which i have done. i have never had one die, the oldest is  32. now which oil?.**
A: I use the 10 30 vanguard synthetic oil in all of my equipment. I am commercial and the mower. Do you use oil because they are air cooled and is to be expected of some usage between oil changes. My units are two to 14 years old and I have yet to have a problem with any part of the engines hope this helps

**Q: Can this oil be used in a motorcycle?**
A: Technically yes, but I would check on the manufacturers specs of the bike before using.

**Q: Does this meet SAE standards?**
A: I would assume so. It is the oil Briggs recommends. Doubt they would recommend sub standard oil
