renxun, u use other oils later ur sponsor company marah ler. heheheheee
hehe... last time sponsored by TOP1... but now not anymore. im back to my own choice of usage.
2 brands of my choice
1) Fuchs Titan Fully syn- reason being is they do sell in 5 litres pack. which ngam ngam for my 1jz
2) Shell Fully Syn- the black colour pack with a ferrari logo outside (used it once and felt its ok.but have to purchase another xtra 1litre as they only have 4 litre pack)
**if i hav the money i would lke to try motul fully syn too ... but too bad i change engine oil very frequent regardless of fully synthetic oil. 4000km - 5000km will change for sure together with filter. thats why using motul at those intervals can quite harm my wallet.
never flushed my engine b4. maybe shall try the shell and see how... my oil is only brown colour every time i change oil...so i shall try and update here wat is the outcome...
how bout gearbox oil? how frequent do you guys change? the last time i change is around a year ago with Q8 fully syn oil + lube guard. nothing to shout about... operation is same.
spark plug wise. maybe im lucky that i dont face any issues although the usage reach around 80k km. changed to iridium denso. and now it had clocked 40k km.... the slight difference is only it felt a bit lighter on low rpm b4 boost kicks in ... other wise its the same...
