I’m curious about long term fuel storage. Does anyone have any experience with these PRI-G or PRI-D ( http://theepicenter.com/tow021799.html ) fuel stabilizer products? They make some wild claims, like making 15 year old gasoline return to “in-spec” condition. I’d almost have to see it run in a...

You have a cool job, NYEngineer.

Thanks for the replies so far. For the first 50K I used all Castrol GTX, but after that I started using whatever 10W-30 brand name dino oil was on sale 4 qts and 2 qts of a brand-name syn to make my own blend – this on the advice of a tribologist who wrote on syn blending. He said mixing diff...

I have a 1996 F-150 4wd with the 300 I6 engine. It just turned over 150K miles. It uses about a quart of oil or a little less in 5000 miles. I have always changed oil with a brand name, often with 2 quarts of syn mixed into 4 of dino, every 5k miles or less. The body is in good shape -- no rust...

Any advice on the best readily available TC-W3 and TFC oils?

Forgive my ignorance here. I’m not too “up” on 2-cycle oils. Is TC-W3 for water cooled engines, but TC for air-cooled? Pennzoil says about this oil: A high performance 2-cycle engine oil meeting or exceeding the warranty requirements of all leading manufacturers of 2-cycle products including...

No, not sure what the outboard's oil spec. is. I used to use a Mercury oil, but only use 5-10 gal of gas a year, so not too much oil. What's left over form the outboard I usually used in the other eq -- after doctoring to the correct mix ratio. This is what the Pennzoil Outdoor says...

Any advice on the best value in this stuff? Is it really a terrible thing to use regular motor oil or used motor oil for bar and chain lube?

I have a 70's era 20 HP mercury outboard that calls for 50:1, a 70's era McCulloch chani saw that calls for 40:1 and newer weedwacker and Mantis tiller. Is Pennzoil Outdoor 2-cycle oil a decent oil for those items? I used to find a synthetic Pennzoil but can't find it now. Thanks for your...
