Upper engine internal varnish on Supra turbo

[aquariuscsm]

I looked at a 1997 Supra twin turbo that has only 60k-ish miles on it. First thing I did was remove the oil fill cap to get a good look at the camshaft. Everything is varnished,dark,and discolored. Oil that`s been used the lifetime of the car is bulk Toyota dino. Is the varnish a result of using dino all it`s life that could`ve been avoided using a top quality grp IV or V synthetic?

Thats a find and a rare car! The car is 12-13 years old - maybe more of a "sunday driver" kinda varnish. Was not toyota oil = EoM driveclean? What weight in the tirbo - hope not 5w30!

I`m not sure on the oil weight,but if I decide to buy it,it`s getting a synthetic 40 weight as soon as I get it home :^)

Probally a result of heat from a forced induction engine cooking the oil. I'm sure quality synthetis resist this heat better resulting in a cleaner engine.

I think Shell Rotella T Synthetic 5w40 would be a perfect choice for this application.

Need pictures of the parts in question. But most important is seeing the body.

Varnish is really no biggie. The syn should help.

Probably from using a grade too low for that turbo!

Still, you should be able to clean that engine up in no time =)

That engine got HOT. And who knows what oil was used?
I'd use synthetic with any turbo engine.
Varnish is not a killer, but a symptom of heat, old oil, or a faulty PCV system.

Please don't tell me you're getting rid of the Z, are you?!

How could one possibly own that car (even though I personally am NOT a big fan of them), and NOT use a top shelf, group 4/5 oil?!?!
I just do not get people sometimes.

Is it BPUed (or more) as well??!!

People think that they could save 10 bucks on an oil change, in a car they paid 25-30 thousand for.

In 10 years, they could be "saving" like 100 dollars!

That is why they don't use top shelf oils.

Try some Mobil 1 0w40 or GC 0w30 or Pennzoil Platinum 10w40
