In the begining having my celica, I only wanted the best for my ZZT231...so I used Motul 300V power 5W40. Man...that's a damn good oil!! Freakin' good! Ur engine felt smooth and u won't feel any power loss. The downside is...argh...it cost nearly RM200 per botol for only 2 liter and since the ZZT required like 4.5 liter, u will end up spending RM600 the first time, then RM400...kekeke! I service my car every 5k and after 3 times services...cannot tahan...koyak liao!! :-)
So, after that I changed to Motul 8100 X-cess 5W40 also 2 liter per botol and cost roughly RM118. Not as great as the 300V but it's sufficent enuff. Then, a tuner told me that instead using the 8100 X-cess, my celica is good enuff to take the Motul H-TECH 100 Plus 5W30 and only cost me RM135 for 4 liter botol. So far so good but I reckon this oil will force me to service my car every 4k instead of 5k. Just want to share my experience and seriously if u want the best, no concern on the bill...then the Motul 300V is definately one of the best oil!!!
