hi just curious as to what oil ppl use in there vls n what they reccommend? im curious as to what ppl say. i am currently running mobil1 5W-50W but after the last cruise th car was running hot.. might be lil thin. the engine internally has been freshened up n only done 35000kms since. some info n advice would b great.

ulx 10/40 in my built motor only cause my builder told me to use it

yeh? wats th cost for 5L bottle? how many kms on ur motor?

It's the radiator and coolant which keeps the engine running cool lol. I'll be using ULX110 10-40 in my new engine

yeh but if ur oil is to thin i been told is causes more friction n creates more heat? could also b my clutch fan...

Yeah oil does contribute, it just a lame bit of sarcasm lol.. It could be many things!

lol i kinda figured that... so y a mineral oil? wat r th benefits? over a full synthetic? ive used penrite 10w-50w before was good i just tried mobil1 this time out.

never had a prob using Penrite 10w-50w before my car came off the road...

have you checked your trans fluid level too?

its manual n it got serviced in march...

i use 20-50 castrol big bore street machine

If it's worked hard on a hot day, it gets closer to 90 but goes straight back down once cruising. I use Castrol magnatec professional 15w-40 in the current un-opened A8

may be due for a new clutch fan n is due for oil change.. mayb a gearbox oil change too... mmmmm mayb need pull finget out n service it.. lol think ill go back to penrite

I use ulx 10/40 find the oil very good tried others ulx has increased my Dyno results by around 6 kw very good on cold starts as well hope that helps a little.

I use hpr30 never had a drama with it

so many choices lol so wats th benefits of a mineral oil over a synthetic?

Mine has always run on valvoline since new.10w-40 in it at the moment. My temp never goes above a quarter, but on standard setup....

Differences are Synthetic oil is artificially designed & made oil in a lab, We're as Mineral oil is basically a crude oil distilled from Petroleum. Ive started using Kendal oils in my vl's and am luving them.

so a mineral oil is better? or r they bout th same?? i think ill just go back to the penrite 10w-50w see if makes a difference... if still same might need new clutch fan..
