Not sure about the 10W-40 for the Esprit engine...

My 88-92 and 93-V8 manuals call for 20W-50 or 15W-50 depending on temperature for the Esprit 4cyl 910 engine....

I have used Mobil 1 15W-50 for years. Will change to 20W-50 for the track next summer. The tappet noise was louder with 20W-50 in the winter, so I switched to the 15W-50, and it sounded better.

Travis - you're correct, and you you would know best... But I was thinking winter in colorado is probably cold.
Having tappet noise when cold indicate that the oil is not flowing, so a 0-30 or a 10w40 might be better in winter???

This can be used with any oil Red Line Synthetic Oil - Motor Oil for Racing - Engine Oil Break-In Additive

Changing the brake fluid occasionally is useful.
When it is water laden it is important to change it. This is cheaper than changing it twice a year.

And Colorado is probably less humid than some areas.

You run your Esprit in the winter? I suppose Colorado is a lot milder than MN. Do you think wider swings in temp affect the cyclic life of the manifold or doesn't it matter much. I always suspected that the manifold would not last as long if you used the Esprit during winter a lot. I always wanted to know when exactly people noticed the manifold cracking from people in different parts of the country warmer/milder as opposed to really colder areas.

My manifold is fine. I often drive it through the winter since we get a lot of nice days, and they don't use salt here.

I also drive in the rain, even a few times in pretty deep water, 4-6".

It tends to overboost in temps below 30 or 20F, so you have to either reset the ECU for colder temps, or take it easy on the boost.

Factory oil spec is 20W-50. With a synthetic it's OK to have a "lower" first number.

The Esprit's engine has generous clearances. That's why you need the 50 weight protection.



Unless you keep it outside :eek: and start it in sub-zero (F.) temps, you will be OK with 15W-50. Make sure it has enough ZDDP to protect the flat-tappets. (SM 0r SN oils might benefit from a ZDDP additive)

The synthetic oil minimizes the chance of coking in a hot turbo. :bow:


Lotus spec's 6000 mile oil changes on regular mineral ("dino") oil. Are you going to do more miles than that a year? If not just change it once a year preferably before you "put it to sleep" for a winter's rest.

When you are changing fluids, don't forget the clutch or cooling system. Don't add anything but Dex-Cool if that is what you have in your cooling system (factory fill from the GM era). That stuff doesn't play well with other types.:mad:

Lastly, don't forget to replace the blinker fluid.

I use ONLY the finest synthetic BF! Yearly, you need to flush it through your system by actuating the hazard flasher switch at least 12 times.
