How much oil is needed for a 2.6 Astron engine?

Answer 1

An Astron 2.6L motor (in my 10 years experience changing the oil on one) seems to like to run with a around 4 and 1/2 litres, 5 litres is a little too much. If your dipstick shows a bit over the full line don't worry about it, they prefer to run a bit overfull anyway and it leaves a bit of room if you've got an unknown oil leak. Any less than 4 and your engine won't like it. Try to use an oil that's not too thick and not too thin, thicker oils just clog them up, thin oils won't do the job and the more expensive type oils just aren't necessary for this engine. Don't use anything too cheap either like freeway oil, it'll just wreck your motor. For the purposes of this post i recommend Valvoline Premium as I've used it for years on my astron and it just seems to like it. i have the astron 2.6 (86) servicing book it is 3.3L when u change the oil and leave the filter or 3.6 if u change the filter i did a change on my motor and it was perfect and that stuff about thick and oil all depends on what climate your in (and it also depends on what astron you have)
