Liqui Moly Street 4T — 5 weights
Liqui Moly Street 4T runs 5 weights deep here — 5W-40, 10W-40, 10W-60, 15W-50 and 20W-50 — which puts it among the broader lines we stock, behind Motul 7100 at 7.

Every Liqui Moly Street 4T bottle in this list states full synthetic on the product itself. Where a bottle does not state its base stock we leave the field blank rather than assume one.
Priced by weight: 5W-40 from $12.92 for the 1 L (2 sizes), 10W-40 from $12.15 for the 1 L (4 sizes), 10W-60 from $21.54 for the 1 L, 15W-50 from $51.08 for the 4 L and 20W-50 from $13.38 for the 1 L (2 sizes). 10W-40 is the cheapest way into the line and 15W-50 the dearest, a $38.93 difference — which is not a reason to pick one, since the manual decides that.
Per litre the spread inside this line is real: the 4 L in 10W-40 works out to $10.35 a litre, against $21.54 for the 1 L in 10W-60. If your engine takes more than a couple of litres, the larger bottle is the cheaper way to buy the same oil.
We carry 2 Liqui Moly lines in total — Street 4T plus Offroad 4T. Street 4T is the cheapest of them to get into, at $12.15. Comparing across them is a fair way to shop; comparing a Liqui Moly grade against the same grade from another maker is what the weight pages are for.
Bottle sizes in this line: 1 L and 4 L. 9 of the 10 are available now; the rest come in on a supplier order. Prices shown are ours and come from the catalog, not a list price.
