Great choice for older vehicles
High zinc oil is recommended for older vehicles with flat tappet valve lifters. Using in 97 jeep 4.0 engine. Runs quiet and smooth in S.C. summer heat. Do not add any other zinc additives when using this oil as too much is not advisable.

Awesome Performance – Perfect for Lawn Equipment
I’ve been using Castrol GTX Classic 20W-50 in my lawn equipment, and it’s been absolutely great. It provides solid protection, smooth operation, and helps extend the life of my mower and trimmer. This oil is especially good for older engines or small engines that run hot and need a thicker oil.The only downside is that it’s hard to find in stores, so I usually have to order it online. But when I can get it, it’s worth every penny.If you're maintaining older engines or heavy-duty lawn tools, this oil is a reliable choice. Highly recommended!
