oil query .

[maccavvy]

Thinking of doing an interim oil change.
mate of mine owns a garage ,but want to get my own products
how much oil and what grade is recommended for a 04 ls1 with 56k miles.

[vxr2010]

I think oil capacity is about 5.3 to 5.5 litres for the 5.7 , use a good oil 10/30 or 10/40 , and a good filter , I was told not to bother with interim oil change if car is for normal use , if I tracked it I would

I'm using Mobil 1 0w40 in mine. 5w30 with ACEA A3/B4 or GM LL A 025 can also be used according to handbook. As above 10w40 can be ok also.

5-30 or 5-40 good quality oil asda do a good price on Castrol gtx mag tech.it takes about 7ltrs.

If it's NA engine, just stick to something like Mobil 2000 and a good quality filter, oil is only as good as the filter it passes through.

found a cracking deal on shell helix hx7 full synth 10-40 .

would this be suitable.

Any decent brand will work , I'm much for a 10/40 as I think other oils are too thin when things get hot , subaru says a 5 /40 or st on those lines , subaru engine builder who I go with says 15/50 , the 5.7 oil capacity is a lot less than the r8 I think r8 is around 7 litres

Mobil 1 , fully synth, £30.00 for 5 litres from Costco, LS2 engine uses 8 litres.

Cheers guys.

picked it up today. 35 quid for 10 litres.

new filter and ill drop it at the weekend

its always been serviced at monkfish but with mileage not age.
so wont hurt to do more often.will still get its official one

[Black VXR]

how many miles has the car covered since new. Monkfish recommend a 10-40 RP after 100K as the engine gets a little looser

[maccavvy]

oops my mistake it is 5w40 not 10w40 . and its done 56k
