About Us

Last updated September 20, 2026

Auto Fluid Oils helps drivers, DIY mechanics and equipment owners choose the right oils and fluids: gear oils, differential fluids, hydraulic oils, motor oils, AC compressor oils, transmission fluids, and the tools used to change them.

Who runs this site

Auto Fluid Oils is run by Eng. Kamrul Islam. I am an engineer by training (B.Sc. in Textile Engineering), and I have more than 10 years of experience researching, comparing and selling products on Amazon. I run my own brand on Amazon Australia and have hands-on experience with Amazon FBA, which means I have worked on the seller side: sourcing products, checking manufacturers and origins, reading thousands of customer reviews, and seeing why some products get returned and others do not.

How we review products

I want to be clear about our method. We do not test every oil in our own garage or workshop. Our reviews are research-based. For each product we look at:

  • Specifications and standards – viscosity grade, API/SAE/ISO classifications and OEM approvals, and whether they actually match the use the product is sold for.
  • Verified customer reviews – not just the star rating, but repeated patterns in real owners’ feedback: leaks, noise, shifting problems, packaging damage, or long-term satisfaction.
  • Brand and seller – who makes the product, who sells it, where it comes from, and whether the listing looks trustworthy.
  • Value – what you get for the price compared with similar products.

We then recommend only the products that hold up across these checks, and we explain who each product is best for.

Always check your manual

Every vehicle and machine is different. Before buying or adding any oil or fluid, check your owner’s manual or ask a qualified mechanic for the exact specification your equipment needs. See our Disclaimer for more.

How this site earns money

Auto Fluid Oils is a participant in the Amazon Services LLC Associates Program. When you buy through our links, we may earn a small commission at no extra cost to you. This never changes which products we recommend.
