What are you using for Lathe Way Oil?

Way oil, if I'm not using coolant oil.
It might not seem cheap but it does go a very long way. I doubt if I get through a litre a year.

I use 68 grade Slideway Oil. As with all my lubricants, I buy it from Smith and Allan. Great service and low prices. 5 litres Slideway Oil is £11.55 plus vat and carriage. 5 litres lasts me 5 years+. I try to order a number of items (Slideway oil, cutting oil, spindle oil, paint etc) at the same time to spread carriage cost.

I too use ISO 68 way oil since a friend gave me a 4L can, before that I used mineral based chainsaw oil mixed with a plain ISO 68 oil. The carriage seems to move slightly more smoothly using proper way oil.

I use a straight 30 engine oil as recommended in my Myford handbook.

I use ISO 32 hydraulic oil; simply 'cos I have a fair bit stored away, in my lathe saddle gearbox I use 10 / 40 auto oil, both work fine for me.

I use 5W40 semi synthetic engine oil, any oil is better than none.

Absolutely, but next time you buy oil look for SAE 20 rather than 5. 5W40 is good for cold starting a car engine on frosty mornings. It works by being thin at ordinary temperatures and thickening up significantly only when the engine warms up. It lubricates best at about 100°C. SAE20 is thicker at normal temperatures and more what we want of a lubricating oil.
IP68 Hydraulic Oil, SAE 20 car oil, and SAE 75W or 80W gear oils all have about the same viscosity, and each is broadly OK for splashing on a lathe. Way oil is distinctly sticky compared with all of them.
IP68 is often recommended. I think it's because Gear oil tends to be pricey because of its high-pressure performance and engine oil might contain undesirable additives. Not that I've ever heard of a machine tool being damaged by an engine oil!

Myford suggest 68 grade slideway oil for the 254S, but don't use it in gearboxes

"Guy Lautards Gunk" - made up of 3 diff oils in diff proportions. Seems to work OK. One is STP or equivalent to make it stick in place another graphite, molyslip to fill any minute gaps with graphite particles and third, EP oil. It's in one of his excellent books.
(He also had another concoction to aid drilling which I have found to be very good.)

DMB what is the drill aid please........

An ISO68 slideway oil on the centre lathe and an ISO32 hydraulic oil on the repetition lathe. The repetition lathe is operated by levers and the slideways are sufficiently close fitting that a slideway oil adds significant drag.

Dextron 3. I've about 3l left over from topping up an auto gearbox(that I no longer have) a few years ago. It's basically light hydraulic oil with a dye, so I'm not going to buy anything else. It's one of those deals where any oil is better than nothing.
