hi all skoda felicia members i have felicia 97 carb and i use castrol gtx 20w-50 http://www.castrol.com/content/dam/castrolcountry/en_my/Products/Car/EngineOils/GTX-Product-Page/GTX-20W-50/4L-GTX-20W50.jpg

my cars make 109000 km i change the oil every 4000 or 5000 km is better to use other oil and thx

I am not a fan of Castrol. Moreover, Felicia doesn't have a performance engine to use fancy oil. Any semi-synthetic 20W50 oil will do. On normal conditions of operation, you can change the oil every 10,000 km. If you have too much money, change it every 5,000.

this oil is mineral oil 5000km the car seems good with it but iam asking does semi-synthetic will work well or i need to flush the engine

if i not found 20w-50 how about 15w-40 or 15w-50 or 10w-30 does it fit the car or not

You can use 15W50 too.

personally I use 10W40

personally I use 10W40

You do because you live in a cold climate country. The OP lives in a hot climate country. Big difference.

thx man

I use Mobil Super 2000 X1 10W-40  on my Felicia 2000 50kw and i change it every 10.000km. On how many km we should change the oils?

So often as your budget allows it but no more than 10,000 km or 2 years.

So the maximum number of kilometres for an oil change is 10.000? 

There is nothing written in stone for engine oils. There are many variables involved. Remember that oil is the blood of the engine.

depending on the oil you use and how you use it, i use semi-synthetic castrol gtx and i change it at approx 5-8k km and the oil gets out pretty damn clean, imagine it still looks brownish

I think that manual states 15k km or one year. I changed after 15k (twice a year), without any issues with the engine and almost no oil consumption.

But if you drive short distance with cold engine, you should stick with shorter interval.

Has anyone used synthetic oil as Amsoil 10W-40 in his Felicia?

 

I change mine every 7000 Km,in the beginning i was changing them at 5000 Km but my technician said ''that is too early".
