In case anyone wants to know, this mornings Sunday Los Angeles Times has an add for Kragen. They show synthetic blends for $1.99 a quart. They list Valvoline, Pennzoil, Quaker State, Castrol and Chevron. The coupon also has a Mobil logo so I would assume that Mobil would be included. Another coupon has Valvolyne conventional oil at $.79 a quart after with a mail in rebate if purchased in case quantity (limit one case). Still another coupon has Mobil 5000 for $.89 a quart after mail in rebate if purchased in case quantity (limit one case).
