Following the album's release, Spineshank toured Europe as support for Fear Factory and
Kilgore in late 1998. In January 1999, the band joined Fear Factory and
System of a Down for a tour of the United States that was intended to end in February 1999. However, on January 23, 1999, the truck containing the gear of all three bands (worth $250,000) was stolen in
Philadelphia and several tour dates had to be postponed to March 1999. Roadrunner pulled Spineshank's touring support following the theft, and it worsened pre-existing tensions within the band. The band later toured as support for Fear Factory, Sepultura and
Hed PE between April and May 1999, and they also made an appearance at the
Dynamo Open Air festival on May 21, 1999, performing on the Gallery Stage. Spineshank's association with Fear Factory created pre-release hype for
Strictly Diesel; Garcia noted: "When it first came out, [the album] got rave reviews. But all of a sudden, it became cool to hate Spineshank, and this was mostly overseas." Both Spineshank and Roadrunner Records ultimately considered the album a failure. In 2001, Decker told
Kerrang!: "I honestly thought it was all over. I honestly thought we'd blown it.". The band were motivated by the poor reception of
Strictly Diesel to prove themselves when writing and recording their next album,
The Height of Callousness (2000), which several critics saw as a triumph over their detractors from this period. The members of Spineshank would consider
The Height of Callousness to be the band's true debut album, as they had not established a musical identity on
Strictly Diesel; Sarkisyan would later call the album a "glorified demo". Despite this, the members of Spineshank felt that
Strictly Diesel was important in shaping the band's future musical output. Santos believed that
The Height of Callousness "would not have been possible without [
Strictly Diesel]". Sarkisyan also felt that "A lot of good things came out of [the album] [sonically]", and that it "didn't get a fair shot" upon its release. There have also been some positive reassessments of the album;
Metal Hammer included
Strictly Diesel in their list of "The Top 10 Essential Nu Metal Albums" in 2016, praising the album's songwriting and Santos' vocals.
Revolver also included the album in their list of "20 Essential Nu-Metal Albums" in 2021, calling it "largely overlooked". ==Track listing==
