Wrong oil ?

[Danny & Margaret]

Hello, we've just purchased a very good example of a 90 Silver Stone Eunos
Roadster.
We changed the oil in the crankcase to Mobil 1 and replaced the manual gearbox
oil with Red Line MTL. Apparently this stuff is rated at 70W80. We've just
discovered later that Mazda recommends 75W90. Will this MTL lube cause
problems if we don't change it ?

Nothin' but the best for your baby eh? cool ! ...I believe either MTL or MT90 is fine. I put MTL into mine as well
