Lotus Eclat Fluids - Recommendations

Hi everyone,

I decided to change most of the fluids in my 1979 Lotus Éclat and wanted to ask for your recommendations.

Oil - workshop manual calls for 20W/50. Can you guys recommend any specific brands that I should use? Since my engine has a few leaks, I assume that it's better to use a conventional oil, rather than synthetic. Am I right? How many quarts or liters do I need?

Power steering fluid - workshop manual calls for hydraulic fluid: Texamatic Type F (1.14 liters / 2.4 US pts). I can't find this Type F oil anywhere in stores. Can you guys suggest a substitute?

Coolant / antifreeze - workshop manual calls for 3.7 liters (which seems like far too little). What type of coolant should I be using that's widely available today?

I'd really appreciate your input here!

Oh man, his is my favorite post of the year

Oil: You should be fine using synthetic, they don't really cause leaks. Try replacing the gasket, otherwise

Tranny/powersteer: Oh my god, you would have to rob a museum to find that stuff. There's some 'vintage' examples online, some of them are even unopened! I doubt the oil would still be good though, and you wouldn't want to ruin an antique would you?
Lo and behold, I found the answer for you! Get any type F fluid, like this one

Coolant: don't stress too much about it, just make sure you do a very thorough flush. Get dex-cool and you should be fine

Your manual is a bit out of date, but the fluids haven't changed all that much

2005 CO Elise: stage II CLF exhaust, B&M shifter, 5.25"/6.5" speakers, footwell lighting, RLS side mirrors, and 2 Dartholders (caffeine injection improves performance)
Uncage your garage queen and quit being a pansy. Daily drive it!

Thank you for your quick input and enthusiasm Swic!

Can anyone else offer their opinion?

Can power steering fluid really be substituted with automatic transmission fluid?

Coolant: the article link you posted provides great insight Swic! Can someone tell me the procedure to get as much of the old coolant out of the system, before filling up with the new?
