i know this has/is done time and time again but....

since having my car converted to LPG i've noticed it uses more oil, first oil change when i bought the car which had fresh oil in it was .5 of a litre down on the first change. i don't know what oil was used, i've used castrol magnetec 10w40.

since having the car converted to LPG which burns hotter and it's now using around 2 litres every 5 to 6 thousand K's

so tomorrow i'm changing to penrite semi synth 15w60 hope fully it will use less oil

BTW the runs like new with no issues

i guess as the engine ages gets modified the oil needs change

hey mate your best bet is to check your service records and just keep using whatever its been serviced with before

so i changed the oil today went from castrol 10w40 which i was very happy with, to penrite 15w60

all i can say WOW, who would of thought oil could make such a difference, the engine is super quite and feels better than ever, not a single tick from a cold start

i guess as someone mentioned above the older the engine the thicker the oil should stay at when at temp

my engine is at 210,000 k

Is that the penrite semi synthetic HPR15? I use that in my VS ecotec and Ive found its excellent oil...fairly cheap too.
