SEMI-SYNTHETIC OIL.

[Anonymous]

Hi all
I just wanted to try and clear something up.Where i got my car from(who are well reputable tuners in jap imports)said i should put semi - synthetic oil in the engine,but i see you chaps are using fully synthetic oil.Does it make a big difference between the two,and if so will it harm my engine if i do use semi synthetic. :?:
Cheers.

Yes - do use fully synthetic

I use 10W60 Millers CFC (racing spec) which is about £30 for 5 litres

Enjoy searching!

so do i gives good pressure and makes the engine sound smoother.

i've also tried casrtol rs 10w60 and agip 10w60 all good oils, i'd recomend any of them, if you have trouble getting the millers.

I think maybe the confusion stems from the fact that when the sr20det engine was being designed fully synthetic engine oil of todays standard wasnt available or too expensive so the engines were designed to run on semi synthetic hence some people still use semi :?: :?: :?:

Hi guys,

I dunno why, but my car has always been running on 10W40 ...
I'm in holland, so same climate as uk.
Now I've always been told once you use semi synth oil you can't change to fully synth oil ? Is this true ?
(oh, and how many litres of oil should I put into the engine?)

i heard it was the other way round! once on fully synthetic you cant go back.

its about 3.7 litres including prefilling the oil filter, but check the dipstick to make sure its full.

ehm prefilling the oilfilter ? And how do I do that ?

 

[andygtir]

just pour some oil into it and be quick tightening it up

Nope. In the old days semi and synthetic used to cause jellification (or some similar effect). Nowadays there's no problems.
