What Oil

I want too do a oil change,  what Oil/Grade etc, should i use in my 1.3 Golf.

Thanks

Asda 15W/40 diesel, about ?7 for 5 litres?

Forgot to mention it's a petrol 1.3.

Yep, the diesel oil is fine in the petrol, it has an API SL/CF quality rating and is in the correct vistosity range. Also its the cheapest around (I think). If anyone knows of any cheaper oil, feel free to post up.

Never heard of using diesel oil in a petrol engine, but you seem to have more knowledge than me re mk1's.
So taken that on board, just picked some up from Asda ?12, and it's going in this afternoon…….so if my car blows up i'll send you the bill

Thanks for the advice,

Bash.

And if it doesn't…….can you send me the ?1.50 price difference you've saved? LOL

Is 10W 40 too thin?

Nope, its fine too. 0W40, 5W40, 10W40 and 15W40 are all the same thickness once its warmed up. When cold, 0W40 is thicker than 15W40 when its warm. The viscosity is an arbritary scale, not an actual measure of thickness.

i ran a 1300cc astra  on 10/40w jcb oil for 3 years and 90k with no probs whatsoever, and last i heard its still going strong 4 years on. only reason i used the jcb 10/40 oil was beacause i used to get it from me dads 40 gallon drum he was getting for plant machinery at the time. more luck than judgement as the oil was free, but proofs in the puddin as they say!!!

Just looked the haynes n it said 15w 50?

Perfectly acceptable. Bought some Castrol SLX Professional to top up recently (dealer used it) and noted that the oil is VW 505.01 approved, but also for use in BMW and Mercedes-Benz petrol engines.

Speaking of that oil - would 5W30 be too thin, or can I safely use that? Could always switch over to 5W40 at the next oil change.
